My shower BASE is cracked and leaking water. Is it possible to change out just the base without having to tear down the tub surround? [ATTACH]56016[/ATTACH]

this pic is from another thread on this forum. but for that fake blue tile wall, can I just use adhesive and put a standard shower surround over the wall. obviously id clean it as well as I could and rough up if that would be needed. once I finally do my shower stall I know I cannot take down that tub wall because it was a mess with a sledgehammer to take out all the shower stuff. and if I put tile in the stall then used a hammer to rip out the tub walls id worry about shower stall issues with new tile. and I have to finish the one thing before I start the other. heck should I maybe do the tub surround first? I have no other bathroom to shower though so would have to be done in a day. however I don't know what to do about that excess wall you see coming out from the tub. I don't have that one foot of wall on the other side of the tub I do not want to take out the tub and as far as the next owners not liking a blue tub, too bad. :) I may paint the upper walls blue to match if I can. unsure yet and no I don't have that shower done yet. still thinking about ideas and how to do it but leaning towards trying tile myself.
