MarketPress doubt

Hi all!

Congratulations for the great new site!

Guys, me and my equip are intendig to make a really nice project in e-commerce market.

We want to use MarketPress to get the job done, but you've got just 4 themes that runs MarketPress natively, so we are going to make a ruge buy of almost 40 wordpress e-commerce themes and we are going to modify the code to fit MarketPress.
Of course there's no way to be 100% sure that we are not going to get trouble, but, there's no problem to adapt MarketPress to another themes right? Is there something we have to take care?

Thanks WPMUDEV!!!!
