luckily his legs don't work so he will never be shown standing or walking...

Well they are already recasting people right and left.
The mountain has been discussed here and is probably a good thing...new guy is huge (don't really care if he looks younger since he will have tons of makeup and armor hiding it all).
Warning: Spoiler! (Click to show)
Daario is going to be weird. He wasn't around too long and now they are going to stick in a new guy? Especially since they didn't get super flamboyant with the hair. People would look past the actor if they just were like "oh yeah, that's the dude with the crazy hair and the crazy killing skills". I actually think this one might be troublesome. Might almost be worth reshooting some "previously on..." scenes to show him interacting with Dany instead of the real actor (or probably just composite his face into some flashback shots).
Tommen will be not an issue (except for the fact that the new Tommen played one of the lannister prisoners that were killed by the Karstarks...but hey, at least we can say he looks like a lannister!). I don't think Tommen has been on screen since season 2 and people will accept small kids needing replacements to continue looking small.
