Thanks Chris. I'm trying to parse what you wrote. Are you saying that the comparison was between

a) 2 small CIMs driving a gearbox

and

b) one small CIM plus one large CIM driving one gearbox (so that the small and large CIM are being driven at the same speed ?

I wouldn't have guessed that from what was written.

If what you say is true, sure that's not optimum. The large CIM's NLS is half that of the small CIM. There's no way to operate such a design efficiently.
