TH5 Mini Max

Basically I have 2 mini accounts I was thinking about rushing with. is it feasible to UG Barch then move on TH level all the way up until th10? UG as many elixir buildings as I can in the process? my plan is to have all the th5 defensive buildings upgrading them to the max, but not placing any future defences. ( possibly doing one this way and maybe one to 11 to rush everything )

What implications will this have on my account, ie war position , holding loot etc? im asking is it do-able really? and will I have any advantage in going this way?

It's doable, it's hard and boring and it's gonna suck to farm. As far as war goes, from my understanding the more you engineer the more risk you have of facing other engineers. If you're cool with that go ahead. I'd have to say in my opinion it's no point in doing it unless you can keep the heroes upgrading.
