I am want to fit a top half Merc 525 /Penta intake with throttle body in center on a 502 lower intake with throttlebody on the side. Possible or not?

Nope, they are not compatible.

The 525 intake certainly flows better but it is not going to provide any meaningful gains on a 502 MPI unless there's other work being done.
