Droid Enhancement won't work because and I quote from the readme 1.8-1.8.1 change list:
* Includes Inverted Droid Feat Gain by Hassat Hunter.
** Fixes the feat gain progression of T3 and Goto being swapped around with the feat gain of HK-47. It's correct now, with HK-47 gaining more feats than them rather than less.
Onderon Museum - I'm not sure. Might be a slippery slope....
Dustil Restoration - It worked with 1.8.2.....not sure about 1.8.3.
HLFP - can't say.....never tried it myself.
Just to be safe, I would reinstall everything from scratch.
