Protect the Gath Team Comp?

Thinking on the new Cho'Gath, I've been pondering new ways to build and play him. I've tried out different build orders for various items, seeing how buying X item first in Y game differs from rushing Z item first in W game. Things like that Like how I practiced Critical Strike Sion in bots to see which build path towards 100% Crit was most viable in terms of achieving my gameplay fantasy (drop kicking everything with autos) while still being a useful tank and dmg sponge/cc bot.

Then I recall a "Protect the Kog'Maw" team comp strategy, where the entire team was more or less revolved around protecting and keeping their ADC Kog'Maw alive so he could just obliterate enemies and clear objectives with impunity. The rest of his team's entire game plan as keeping him alive at the expense of their own kda's. Well, with Cho'Gath's power scaling shifted into the late game and being linked to his maximum Health Pool as opposed to AP, how about.

A Protect the Cho'Gath team comp strategy? My immediate first thought, is I'd either be top que Cho and ask our ADC if they would not mind going top. So that I may go bot, giving me access to more chances to feast (2 enemy champs, possible jungler) and protected of support in my lane. Or, queing directly as ADC Cho'Gath and requesting that our Top laner play a marskman, since I intend to play Cho. And to let my random PUG know I wish to have a Protect the Cho team comp.

Ganking a Cho bot wouldn't be that bad, he has a silence and a conditional knock up on q in addition to his support's CC. Cho can alway push like crazy for a turret First Blood if the enemy bot backs. And post level six Cho'Gath's 1000 true dmg nuke to dragon would make securing it a very easy thing to do. When team fights break out, Cho would serve as both a Dmg sponge due to his Health Pool, and a frontline dmg threat. As opposed to doing dmg at range with a frontline to protect him, he'd be the front line with a back line keeping him buffed up and sheilded.

Like in Team Fortress 2, how the Doctor can Over Heal the Heavy and allow him to go on a rampage. When the Cho player gets low and has to recall, the rest of his team should help cover his retreat, and as he recalls and returns to lane the team should play safe and pokey until the Big Guy returns. Obviously I'd need the consent of my team to work with me on this, but right now i'm checking the community waters to get an idea on even how willing people would be to try this.

This whole idea is sort of a problem solver for me. When I'm in any role other then Top, there's still a good chance someone will play an ADC Top anyway And when I play Cho'Gath, I'm prepared to never get a gank from my jungler and ready to get camped all game long. This is something I am ready for but it is a bit frustrating to have this situation while growing accustomed to Cho Gath's new gameplay. Going bot, I feel not only would I have a much safer and healthier time adjusting to the new Cho, but I feel the position and role could actually provide a legitimate tactical strength to the team in such a way that shouldn't bother others.

Why bring Smite bot lane when my champions ultimate does the same thing a lvl18 Smite does, at lvl6?
