Not only the "Red side", I also would love to have an Su-27SM, or even the MiG-29M2, however, the reason why ED is not creating something like the Su-27SM is likely because of restricted info, license, etc. So IMO there would be no problem with an F-16C/D B52+ to DCS.:)
P.S: AFAIK the DCS F-15C is currently using the AIM-120C5, not the AIM-120C7.;)
