Would it be an overkill?
It's part of the evil plan.
(I think there is a typo above, shouldn't it be alias a(T) = b!(T,
known_type) ? )
You mean you would no longer need the surrounding template declaration?
i.e. the above (corrected) statement would be short for:
template a(T)
{
alias a = b!(T, known_type);
}
That would be certainly very un-evil ;)

Being evil would be:
alias staticReduce(alias F, alias Init) = Init;
alias staticReduce(alias F, alias Init, T...) if (T.length != 0) =
staticReduce!(F, F!(Init, T[0]), T[1..$]);
// ^ support conditionals?
enum addSize(int total, T) = total + T.sizeof;
// ^ yeah why not generalize to enum too?
static assert(staticReduce!(addSize, 0, byte, short, int, long[2],
float, double) == 35);
