Sorc boots are usually better than Ionia boots because 15 mpen is the equivalent of 7.5 mpen quints or 17 mpen reds or 24 mpen blues. Whereas 10% CDR is attainable with just 6 scaling CDR blues. The only reason to get Ionia boots is for the 10% CDR on summoner spells which I don't think it's worth it because you're unlikely to use your summoners as soon as they're off cooldown making the summoner spell cdr a bit of a waste most of the time.

You really shouldn't be needing Tear of God and Zhonyas unless you're positioning very very poorly. Seraph's Embrace really only shines in a build that's stacking mana but you're not building any additional mana. If you want to be tankier you should just build a Rylais or even a ROA. Seraph's shield is only equivalent to your current mana which will likely be small with the build you described.

Liandry's is almost a must. Gives mpen and double burn on pretty much everything in Vel'koz's kit.

Voidstaff is almost a must unless the enemy is building no magic resist at all but even then it's usually worth it to cut through the base values on tanks.

Most games I'd say Deathcap is more important than Zhonyas.

Ludens is really nice to fit into your kit if you have space. Gives you a lot of movement speed and a decent bonus when you're sieging/poking. Adds Liandry's burn.
