Probably not a complete answer, but may be setup the mouse and touchpad for left handed and then work on touchpad to get it right handed.

11 is my touchpad id and is currently set up for right handed :
I have not fully tested, changing the mouse/touchpad menu works for me, but freezes my session that becomes completely unusable, I have to restrat LightDM from a virtual terminal. This is an unrelated issue I think as I had the same effect tweaking the keyboard the other day, and I now think it comes from me exiting ibus to have text input into Chromium working (there is a bug about it).
