It is unlikely that the Olympus flash can be adapted and still work TTL.

And, I prefer a single flash mounted at the lens front end at the "10" or

"2" o'clock position and pointed directly at the subject for macro work

This provides soft light for high-magnification work, and avoids the dual

shadow effect that results from using two flashes (and it provides more

"modeling" than a ring-light does...). Some examples are at
