If by "that agent", you mean Keith, the recently introduced agent from OogleFans in SoA, then no, Vi will not be meeting him anytime soon. She will be visiting Bruce, as hinted at in the last MNGF Chapter, and might, at some point (we don't know when yet), do a shooting where Luke (SoA's main protagonist) would be present. But this is all still hypothetical at this point.
Vi (or any of the MNGF characters) will not be exposed to NyctX. There won't be any major plot elements shared.
Do not see more behind Maki's visit to a Nyctora City nightclub (in SoA), or Kate visiting Neon Club (in MNGF) than a good-natured cameo, a tip of the hat from one dev to the other.
Vi is not "working in the same modeling agency", she just took pictures with a professional photographer (Bruce) who shared it with his friends. One of them happens to be a talent scout for OogleFans, and will just try to have her post some content on the platform, that's all.
