In so far as the tile adhering to the wall, sure, it'll work. Whether or not it'll stay there depends on the amount of water hits that area. It's your shower so you'll need to determine that, but be honest about it with yourself and don't take labor into account. If the area is going to be subjected to lots of moisture, better safe than sorry.

Tin, I'm not following you. If you are using a CBU it should be on all 3 walls that your tub adjoins too. The CBU should sit about 1/8" above the tub flange unless the flange is recessed in the studs, then the CBU should sit 1/8" above the tub ledge. This gap will prevent any water wicking up into the CBU. You will tile down to the tub ledge and leave a gap between the tile and tub and fill with matching caulk.

Oh thats fine. You can tile that. I did the same thing. That area isn't going to see much water or any at all.
