I do like the Raft for a tower. However it should be free and should not attack. Instead it has the advantage to place towers that don't go on water into the raft, so it can attack from water.

Raft upgrades -

1. Dart Monkey: the Raft contains a platform fit for a Dart Monkey ($215/$250/$270)

2. Boomerang Thrower: the Raft's platform is larger and the Dart Monkey turns into a Boomerang Thrower ($1575/$1850/$2160)

3. Super Monkey: the Raft's platform is decently large and turns a Boomerang Thrower into a Super Monkey with Laser Vision. ($6750/$8000/$8730)

4. Sun God: the Raft's platform is superhuge and turns the Super Monkey into a Sun God. ($25700/$28090/$31600

However I don't like the idea of a Titanium Bloon, and a Robo Monkey is half Super Monkey half ROBOT killer of death. I don't think there should be a Robot Monkey, but a Machine Monkey could be good. It is a monkey-shaped machine that shoots deadly sharpended screws. and it also has the upgrades of your idea of a "Robot Monkey". No offense, but they'd have to replace Robo Monkey if there was a Robot Monkey in BTD 6.
