Yes - we stuck a Williams Mike mechanism under a Lobaugh Berk. We could do the same for you. It did not cost much - I got to keep the leftover parts.
I did tell the owner that he was converting a $400 Berk and a $300 Mike into a $100 conglomeration, but that's what he wanted. I can offer the same deal to you - I get all the spare pieces. I even have a $300 Mike in stock.
But do what Ed says - get a nice display case!
