Quite a few things have changed since the last time I read Imoen's kit. Most of your additions are fantastic -- I absolutely love the idea of discovering secrets in enemy territory, and having Imoen "lock" enemies fits both her niche and her theme very well. However, I also have some criticisms: the passive is even more monstrously complicated than it was before, Spelljack kinda feels like the odd one out on her kit (it kind of makes her want to dive into enemies, when she should be more sneaky), and some of the details to Cache!, namely the part where you get to create your own, should probably need some more looking into. I'm also beginning to think Imoen might not be so well-suited to be a marksman, and I'd instead recommend making her a full support, possibly even melee (and squishy) to fit the thief archetype even further.
 * The only bit I really like about the new Unlocked & Loaded is the stasis, which is a fantastic effect, and even then I think it could be implemented differently. The rest is a mess of gates and scalings and steroids that don't feel all that appropriate or intuitive, and it's partly because of this that I think Imoen should probably just be a full support (and the first squishy melee support in the game, too), with some Assassin-y elements (in stealth, anyway, and not burst or any kind of damage), rather than a marksman. I'll elaborate more when talking about Treasure!/Cache!, but I think you should move the latter to her innate, with some adjustments, and move the enemy lock into an active ability, namely a replacement for her E.
 * Rogue's Passage is mostly unchanged, and still looks fantastic. I don't think the keyhole interaction really carries that much gameplay, and I'd do with it to avoid piling on complexity, but that's a minor criticism.
 * As with Rogue's Passage, Keyhole is a wonderful ability. I'm not entirely certain what the keyhole object is meant to add, though: is it so that Imoen can use her W more frequently around specific areas? Is it visible to enemies?
 * Spelljack doesn't really feel right. Practically the entirety of Imoen's kit, as well as her theme, is about her trying to be stealthy and avoiding direct confrontation with her opponents, but this ability mainly encourages her to jump into the thick of combat and plow through an enemy. I don't think the idea of a magic-absorbing shield really needs to exist on a more vision-based, sneaky champion, and I'd instead recommend a different ability altogether. Why not, for example, have Imoen's E stealth her, and allow her to channel for a stun while following individual targets during that time? I'll probably elaborate more on this in our conversation, too.
 * Treasure! / Cache!'s core mechanic is glorious -- I love the idea of infiltrating enemy territory to search for secrets, and it fits perfectly with a thief/rogue-type champion, and would complement the rest of Imoen's kit by making her a great roaming support. However, for an ult, the effects feel kinda meh, and the active doesn't feel quite right: a mechanic like this should be about discovery, and discovery only, and the active looks like it could be easily abused for free gold generation over time, perhaps even a heal in lane. I also object to having this provide team-wide gold, because that would give global power to allies without them really participating in it (global gold from towers, by contrast, is fine, since they run on their own rules). The critical strike buff and passive refresh are obviously both tied to Unlocked & Loaded, so I think you can get rid of those, and the heal doesn't feel like it could be the best boon to give, since Imoen herself might not benefit much from it if she discovers the cache "properly" (i.e. without alerting enemies). I think this should be Imoen's innate, and instead of a heal I think it might be better to instead have the caches provide a massive decaying movement speed boost, with Imoen activating the caches for her team later upon discovery, which would work both in and out of combat (Imoen gets to roam further or return faster, and allies in the heat of battle could have a chance at either escaping or catching up to their targets). You'd therefore need to give Imoen a new ult, which I'd love to discuss with you both in the replies here and in our discussion.

Overall, you've made several major improvements and added several more phenomenal ideas to an already brilliant kit. Imoen is truly a unique champion, and it shines through practically all of her abilities. There are a few facets of her left that need a bit more polishing, but you have a champion with an amazing theme and tremendous potential for new and fun gameplay.
