That is not a big problem, and that is what the team and -devel are for.

It sounds to be usable, but I strongly suggest to have it switchable.
I.e. you may switch between current behaviour and new one. I believe
that only testing may help here.

On the question whether it will fit current games, I would tell with
certainty that not all of them. Besides the fact that some engines and
even games do something special with the mouse (consider FT and COMI
showing their action menu after holding the mouse), any future engines
may bring something completely new.

What could work for sure here, is that when somebody finished the
keymapper, and then special events could be generated by the actions
you mentioned above and then mapped to standard mouse clicks on
per-game basis. In the meantime, implementing alternative "clicking
layout" could help resolve the situation.
