I'd go top if I was you. They have a surprisingly good sustain if you build around it. You could have a little problem in assuming the role of the front line in teamfight (since you're top) but you should manage it with a few armors and good positioning, as you will probably have longer range then the enemy front line forcing them into poor positioning. As long as you wrap your mindset around it. But since you're top you probably get that.
The major flaw with bringing kindred mid is that they are AD, the jungler is taking dmg from the jungle camp he have to build some armor, the top have to deal with a long lane and an higher risk of being ganked, he need some armor and the support have a lower budget and you shouldn't count on him for the damage. Which leave the mid, the last position possible for a magic damage dealer. Unless all those 3 roles are simultaneously AP, you will need more magic dmg on your team comp in order to force the enemy into itemizing MR. If they can save that item slot for something else, it gonna hit you in the back later in game in teamfight.
