I don't see that as much of a hurdle seeing as any template written has 
a few "obvious" types it'll work with. To encapsulate that if needed:

struct Awesome(A, B, C)
     private enum ut = is(A == int) && is(B == int) && is(C == int);
     unittest { alias Awe = Awesome!(int, int, int); }

     static if (ut) unittest
