I haven't played around with it fully, but it seems like the 
following resolves my issue in a sort of manual way:

template Process1(A, B)
{
        static if (!isIndex!B)
                alias Process1 = A;
        else
                alias Process1 = B;
}

template Process(size_t n, A...)
        if (n > 0)
{
        import std.meta : AliasSeq;
        
        alias B = A[0..n];
        alias C = A[n..$];
        
        static if (n == 1)
        {
                alias Process = AliasSeq!(Process1!(B[0], C[0]));
        }
        else static if (n > 1)
        {
                alias Process = AliasSeq!(Process1!(B[0], C[0]),
                                                                  Process!(n - 
1, B[1..$], C[1..$]));
        }
}
