Makes sense. Though, is there any particular reason to be hostile to the IMG as a whole and not just the CR? I don't think the entirety of the IMG (indies and the actual IMG player faction) fights the wars of the CR, do they? I wouldn't expect a bunch of miners and artisans would care too much about the machines without the CR's background. Maybe try for neutral with the regular IMG, moved to unfriendly or hostile if that's the way the cards fall.
To be honest, if it wasn't for the CR I'd suggest the IMG as one of your friendlier factions, like the Zoners and Junkers. They all share similarities.
