I dont understand what you want to achieve so I can't recommend something 
based on that but strictly speaking about the issue, fooFO receives a 
template template parameter and not a type so you cannot give it an 
instantiation of MHBase, you probably want to give it MHBase. So:

FooFunc ff = fooFO<MHBase>(*this);

(even tho I don't understand why in that case fooFO is made to receive a 
template template parameter being defined inside MHBase, you do not need the 
flexibility of being able to give it something else than MHBase do you?)
