Do it yourself

Hi! I read through the archives about DIY textured ceilings.Sounds easy enough. But wanted to explore other options...if I have any as well. I am redoing a bathroom. It has a very outdated drop ceiling. I tried to texture it and decided it was not the affect I wanted. Then Dh came along and said lets just buy new tiles. So off to Home Depot we went and got the replacement tiles. Then in removing them I discover the orginal ceiling in tack with great molding and all except for 4 of the tiles. There appears to have been a roof leak. Instead of replacing the ceiling they just installed the drop ceiling. I am sure I can not find replacement tiles for the 4 tiles (10 X 10) (circa the 1950's) but with all the new products on the market is there away to repair them or some other more up to date alternative. I am wondering if the damaged tiles would hold the weight of a texture? Thanks Guys! Looking forward to your ideas and input! Lady paintedlady@...
