Method overloading without Type2Type

Almost. Maybe to allow addressability with pointers the minimal struct size in D is 1 byte (0-length fixed-sized arrays may require zero bytes on DMD and 1 bit on LDC):

struct Type2Type(T){
        typedef T OriginalType;
}
static assert ((Type2Type!int).sizeof == 1);
void main() {}
