I like your thinking. You could actually build suppressors for many different firearms and reuse the same adapter for each of them and only pay $75 for the adapter and $200 for the stamp once but potentially have a dozen suppressors or more.
Thats if your laws will alow it normally if something seem's easy its not going to happen.
But you will only be able to build muzzel forwerd supressors which will make your rifle a bit longer. Most comercially built ones will come back over the barrel a bit reducing how far forwerd they need to go to get the capacity required.
