If you can, I would recommend using the IMU data format. I would not see
the raw data topics as being as important.

Only one driver can access the wiimote at a time, so it ends up
requiring a monolithic driver. I suspect that in the case of your phone,
multiple drivers could simultaneously be accessing different parts of
the hardware, so I suspect that a single monolithic driver is not
necessary. In that case I would recommend splitting it up into
independent components whenever possible.
What to group into a stack is mainly determined by how you want to
manage releases. The model of one stack with separate packages for each
"feature" sounds fine to me.
