I tried making some the other day with this:
10% avocado oil
10% cocoa butter
10% shea butter
15% coconut oil
25% olive oil
15% castor oil
5% jojoba
10% grapeseed oil
at 5% superfat
One I did plain CP, then I did a second batch HP and back-adjusted the pH with citric acid solution to neutral, just to see if it would work (I've heard people say that shampoo bars are bad for your hair because of the high pH). The pH 7 HP soap did in fact suds just fine, but I had to add so much water with the citric acid that they're going to need a couple months to dry out properly before I can really tell if my hair likes one or the other better.
When I make another batch I'll use less types of oils... I went a little overboard.
