Change unit's properties ingame

[Bonzo]

A simple question: Is it possible to change a unit's or ability's properties while the game is running?

For example set the maximum life of a unit or change hotkeys of spells ingame?

If anyone has other solutions for these two examples it would help me too.

You cannot change hotkeys.
You can remove the ability and replace it with a different though.
