Hi wireframex,
For the keymap i don’t know, but there are already some XSI themes around. Remember, everything Blender also works in Bforartists. You just need to take care that the theme is made for Blender 2.80 and higher 🙂

Kind regards

EDIT, here seems to be a XSI keymap available: https://www.youtube.com/watch?v=_DvM009LaN4
