@ciane TS4 introduced some great building tools and it would be good to have them in an upgraded TS3. I suppose a lot would depend on how much the game engine could take even with a rewrite and upgrade to 64 bit. Modular furniture definitely would be worth having. MOO does such peculia things to the existing unmodded game that I have given up using it. Windows that you can place anywhere with the animations to open and close them is on my wish list too.
I don't see any harm in revisiting the CASt just as long as EA keep it as an integrated part of the game. I know it isn't the easiest thing to use but we both know a lot of that is practice. If we are looking at dropping textures and restricting colours to primary and secondary then I think the ability to import our own swatches should be made easier. One of the things players will need to except is an upgraded TS3 needs is a computer with sufficient power to run the game properly. CASt works better and is more stable under these circumstances.
Clothing in the game is so plentiful and that's before you start down the cc route. I wouldn't mind losing some of it providing I had the integrated ability to make and colour my own outfits.
