Oh, definitely! If it needed to be done and Ravi showed an aptitude for learning things on the fly, Aaron would definitely take advantage of that. I'd say they're on good terms for sure: I can't think of a reason Aaron would have anything against Ravi.
As for whether Ravi volunteers or not, that depends. They likely fell out of touch after their time working together ended, and if you want to play out them recognizing each other/realizing they're both in Locke City, then Ravi could start volunteering at a point in-game. If you want to say Ravi heard about Dr. Strider's clinic a while back, then that's cool too, and he'd know the other doctor there (Mordin Solus, testsonseashells) and a young man who works there part-time (Julien Sakazaki, espigeonage). Up to you!
...also bear with me, running this character has been the saga of Krystal-desperately-does-internet-research-on-the-military-and-medical-stuff, since I decided on a concept I had zero background knowledge of /)(\
