I didn't make it!
is it possible to raise the level cap on kotor beyond 20 via a simple edit of a file or does one have too make a mod to do that?

The level cap is hard-coded and thus can't be edited. Sorry.
It has been some time.

However you could do an alternate levelling up. Like making the game check your experience and when you get enough experience a dialog will appear that asks you to choose what skills you want to level up. However Feats and Force Powers can't be added trough dialog, so you would have to stick with skills upgrading only.
