Hello Ganja,
I also like both hulu on the left, especially the upper one may also look good with your ensemble. But I agree that the lower right one is probably the nicest (and apparently quite old) example with interesting pendokok!
Short of an authentic Bugis blade like Rick's Sepokal, you could also try to find a fitting Javanese blade since trade blades of good quality are pretty frequently found with keris from Sulawesi...
Regards,
Kai
