The only way this happens is if the Knights overpay big time for the Wolves, as it's not like they could force them to move without owning the team directly. The Wolves have a solid and deep local ownership with an entrenched fanbase, they're staying unless Vegas makes them a non-violent offer that they can't refuse, and even if that happens Rosemont then becomes the new frontrunner for another AHL franchise.
As for Rockford, they're very tight with the Hawks and it's an insanely easy place to send up and down prospects. Rosement is closer, but let's just say that the relationship between the two groups is still frayed so I highly doubt any amicable partnership there. The only alternative that would make sense for Chicago would be to promote their ECHL squad in Indianapolis to further entrench their foothold in that state, but I'm not sure that has a viable enough of a return compared to the longer travel time for prospects.
I'm sure that the Knights want a closer affiliate, but I'm not seeing the Wolves or the Hogs being on the chopping block of relocation for doing so. Maybe their next affiliate when this one ends.
