I think what you're asking is, "Can you build a NON-donor car?" A resounding "YES!" would be in order.
I and many others have taken the non-donor route and it is very doable albeit somewhat tedious as there is no "central list" of exactly what is needed, i.e. bolts and sizes, various fittings, etc., etc., etc. It is a "learn as you go, measure twice, cut once" ordeal. Would I do it again? In a heartbeat!
Good luck!
