Sorry for the late reply.

Probably so. I've actually seen people on Reddit theorizing that Rico will make a return (we're probably going to be seeing more people from the Military now) but the coincidence is probably ending there. Some characters are made for a one-time purpose and that's it. ¯\_(ツ)_/¯

* Edit: After going back and checking Rico's page, I realized that I lied. She appears in every arc after Trost, so it's actually quite likely that she may make another appearance that counts under either the Marley arc or the new one.
