I was hoping that adding generics to objcclass would be relatively trivial and just hadn't been asked for, but I know how assuming that usually goes.
Hmmm It sounds like once again Pascal needs "traits" or some other way to do composition? I'm extremely keep to develop such feature if the team wouuld decide on some syntax and principles (I had a thread about this some months ago if you search).
In mean time I guess you could try include files and ifdefs in some clever way. Not pretty but maybe it's better then keeping lots of duplicated code or doing big refactors.
