Going by the fatty acid profile on SoapCalc (which is much more revealing than the 'soap qualities' numbers on SoapCalc), you can narrow down your oils without changing the fatty acid profile, which would give you pretty much the same outcome in the soap. If it were me, this is how I would tweak it:
45% Olive Oil
18% Coconut Oil
12% Cocoa Butter
10% Shea Butter
10% Rice Bran Oil
5% Castor Oil
I know most folks consider adding olive oil and rice bran redundant, but call me weird- I actually like using them together in my olive oil soap because of the higher linoleic acid content that's present in rice bran oil compared to olive oil.
I agree with the others, though, that the 1% jojoba is not worth adding. It doesn't bring anything to the table at that low of a %, and it won't help to give soap a longer shelf life (I'm not sure where you heard about it being able to do that, but unless I've missed something over the several years I've been soaping, I would file that under 'soaping myths'). For what it's worth, lye-based soap has a very long shelf life. I have soaps over 10 years old and none of them contain any jojoba.
