Horns go from F to BBb and the tubing is alot smaller in diameter.
Mouthpiece is a whole lot different than tubas too. It has been tried and Miraphone does not make BBb tuning slides for CC tuba.
It is not that easy. Leadpipe length is different on both tubas as well.
Also if he has an older Miraphone and it sounds like he does, he has a 2-step 5th valve slide and if held down he will have an A tuba and not a BBb. If he tries to use the 5th to convert it like the 2165, Culbertson 4098 and the Getzen G50, it will not work. So the only way he can do it is to make all the slides work and add 2 feet of tubing(which is missing to make CC) somewhere.
This is not that easy to do. Sounds like it should be but it is not.
