well, the easiest solution that comes to my mind is:
- the Aurora based Neverwinter Nights had a feature called "automatic quicken spell" that allowed the player to attack every round - in combination with using hotkeys for the spells it was a much faster paced experience.
And as you might know, in Kotor we also can use Spells via Hotkeys e.g. 4 = supportive Powers like heal, R = standard attack, 3= currently selected offensive Force power...
If its possible to assign all available force powers to hotkeys in a separate menu, enabling every round attack and shorten the time for every round to <3sec. should give a more satisfying feel to combat already.

That said, nothing comes close to actual real time combat though. Honestly, if managable, that would be perfect. For balancing, i think Jedi Knight might be a good reference - in general, blaster bolts & lightsaber should be deadly, like 1 hit kill. With the games progression, in later stages (jedi master lvl) you should be able to block most blasters easily.
Lightsaber fight would be very interesting if every strike is blocked/ dodged.
-If the saber is blocked, fight goes on until either Combatant is hit e.g. with critical strike which kills him on the spot. (if relevant stats STR & DEX are similar ).
-If the saber is dodged, theres a good chance for a counter that kills the opponent immediately (high chance to dodge if STR & DEX are much higher)
However , if your opponent is much stronger than you, you are overpowered & will die from the first hits & vice versa (if relevant stats STR & DEX are much higher).
About balancing this, i tried out a very similar existing mod once, "the super enhanced mod" with on hit kill blasters & Lightsabers, with no other mods installed, where i got 1 shotted from Peragus Mining Droids, but as the game progressed the character development felt very balanced & rewarding with everything else stayed vanilla. (the Defence bonus from Handmaiden felt huge and the moment you got the lightsaber was incredibly relieving, also things like stims or grenades suddenly becoming essential).
So, with weapon stats like in the SEM the game & everything set to realtime the game should be already quite balanced i think, quite sure there are mostly minor tweaks to be necessary afterwards.
