He could finally go out with Firestar now that she's out of school and her engagement with Justice fizzled out. Or he could bond with Namorita about being clones (maybe they could set up Water Snake and Kaine on a date). Or bond with Speedball about that time he was replaced by a clone from the future. Or find out if Hornet 2.0 is really Hindsight Lad (or maybe he's just lost in Marvel limbo forever). Or he could hang out with Nova and talk about what it's like for everyone to think you're dead for years.
I think that Ben Reilly needs to continue rediscovering himself before meeting up with old friends. From a story point, I think that 120 issues are needed.
