good way to cede complete control of dragon. would help you against lane bullies in top but not having the extra farm and level income will hamper your scaling even more than just having one lane getting fucked up by a Jayce.
Since you'd be trading level advantage in top, a carry top probably isn't viable, so you're picking like a tank/shieldslut toplane with a hypercarry adc/tank support. Midlane pick gets weird since your whole comp at this point is dedicated to lategame teamfighting and basically ultra "protect the adc". mid roams and snowballing isn't your win condition, so you pick shit like Azir or Corki and just stall.
enemy jungler if he's not retarded is just going to camp your botlane and punish the lack of a man on botside to set one of your carries as far back as possible. he'll be up in levels from farming, enemy top will be up in levels from just not having to share exp and a competent enemy team will just pull this shitty idea apart with splitpushing while you only have one carry in mid that can fight anyone, ever.
