Folio Society basically already does this, at a premium price. Used copies of well-set PD classics from respected publishers like Franklin Library or Modern Library go for pennies and can be shipped to your door fron places like Abebooks, or you can easily find them at your nearby library sale/used bookstore/charity shop/etc.

I've been toying with the idea for a while but I think the market is just too saturated, even for premium editions. Maybe the focus should be on reviving more obscure works... not sure.
