There are a couple of problems with a setup this way:

1. A dedicated counter jungler is super risky. If they can't safely establish control of a section of the enemy jungle - because they got caught out by an enemy laner, or because the enemy jungler is strong in early 1v1 scenarios (e.g. Lee Sin) - then they will lack their own resource pool of gold and experience and will fall behind heavily. They will then have to take resources from their own jungle and will reduce the resources gained by the actual jungler, so you now have two players on your team with lower gold/experience than your enemies. It can work, but it is risky and the point at which it fails or succeeds happens so early on that it is difficult to recover from.

2. Mid ADC, as we have seen for a while, is a thing that works fairly reasonably but you have to keep in mind that midlane is the most gankable lane on the map, with a total of 7 entry points where you can walk into the lane (not including coming from behind the enemy's tower, or over the wall at the raptor camp). Majority of ADC's lack safety features that can repel getting camped from the jungle - mobility and/or strong crowd control. You can avoid this problem 80% of the time with proper warding and not overextending, but some junglers are really good at forcing the issue pre-6. Vi, for example, has one garunteed gank where she flash>Qs into you, at which point you usually will have to blow your own flash. Then she comes back at level 6 with her ult and garuntees a kill. Mobile ADCs like Ez, Corki, and even Lucian can get around this with their mobility, but then this usually involves constructing a comp around using these specific champions in the midlane. Another factor is the advent of assassins - ADCs should be spending most of their time running away from Zed, Fizz, or Leblanc. Now you want them to spend 12 minutes in lane with these guys?

3. Bot lane solo is very doable, but majority of soloqueue does not have the practice of working around this kind of handicap. I would rather put a safer, long range mage in the bot lane than a melee top tank. The first reason is that as long as they can stay in lane, they can still absorb that solo lane experience, and Mages can scale arguably well with levels alone even with a slight gold handicap. The other reason is you want to have your carries close to the dragon pit for the early game so you can contest it - top laners are used to taking TP by now, but mages may rather take a combat summoner like ignite to help them snowball if they can. And lastly, the side lines are considerably longer, meaning your squishy mage will have to venture much farther away from their tower, and if the lane freezes in the centre they will be exposing themselves quite horribly. Plus it takes longer to return to lane from base, causing them to miss out on a lot of experience whenever they have to back.

I did a game once with a duo-bruiser toplane, where I went as Nasus botlane with exhaust and ghost. It was pretty brutal; the enemy team pushed us in quite far and I'm pretty sure we lost all of our outer towers by 30 minutes. The only saving grace we had was that our Veigar reached the point where he could one-shot the enemy Vayne, at which point the rest of us got tanky enough that we started winning teamfights. But it was still very close.

The central reason why we have a 1-1-2 setup with a jungler is because this reliably maximizes the use of the resources available on the map. You can bend this meta to some degree and find success, but the meta of the 1-1-2 + 1 is unlikely to ever really be challenged - not because people are unimaginative or lazy, but because given the resources of gold and experience and dragon on the map, it makes the most sense. The closest we have ever come to challenging this is early season 4 when the runic shield was initially released, and people found a way to abuse the gold sharing mechanic. The only other way this would change is if the setup of the map itself changed; changing the number of jungle camps, changing the minion waves, even moving certain camps or objectives to other areas would likely result in a breakdown of the classic meta. But until then, your stuck with seeing Thresh in botlane.
