I have a base class...

I believe a short version of your question is: "How can I get multiple inheritance?" The short answer is that Objective-C does not support multiple inheritance.

Any solution I've missed?

Re-think your design so that the required ivars can be stored in a delegate. If desired to make it more fool-programmer-proof and reuseable, declare the delegate with an informal or formal protocol.
