If you're not committed to a 1911 platform, an HK45 Compact for $699 would require no modifications for use with 45 Super and likely would be cheaper than the Kimber.
The concerns I have with running 45 Super in my Colt Commanders are frame battering and the possibility of the slide outrunning the magazine during the recoil cycle causing a feeding jam. I have not tried 45 Super in my Commanders because I have HK's for that purpose.
