The biggest problem is mechanical, like mounting a switch in 
the amp. It's pretty easy to handle the rest.

I think you are asking for more problems by using a 
transplant because none of the component values will be 
correct and the mounting aspects might be worse.

Why not find a switch and then build around it? There isn't 
any law the switch has to be ganged to the tank switch.
