According to a quick search that's around a $2,000 bike. No way would I personally go modifying something like that that extensively. You can end up changing it into something both unrideable and unsellable. Nothing wrong with changing the tires, nearly no risk for that, but more than that I've seen "conversion" projects go bad so often...if I wanted a different bike I'd buy a new one that already has the stuff I want and sell the old one.
