Ive had a couple of ideas
1, a stylalized number at the bottom corner, kinda cheesy but it works.
2. by using different icons given in SWTOR to show a "progression" The Inquisitor lightning zap icon for force lightning level 1, another for level 2, and force storm for level 3. Honestly this is a vodka fuled modding spree, Ill likely want to rename/replace certain icons in a few days with a better version, for now I'm just gathering the icons I need and reading up on Tga/tpc overwriting/conversion. Notably if the icons dont need to be resized its ok, if not, I'm going to have to load up gimp and replace the vodka with some coffee for the next few hours.
Managed to get a test Icon successfully in game, (though not the one I will use for dual weilding) now it is just a matter of properly implementing the rest.
