This is gonna be a long-winded 'No', but...:
This reminded me that I've contacted Krylon a couple of times to ask about any sort of FS matching. No reply that I can recall (about 4+ yrs since last, though), but why not write to them directly? If you can get FS numbers on the Krylon, then just hit the ipms site. I think I asked on two or three other model forums as well, and a few of the WWII aircraft guys have good leads if you're looking for a few of the tans/browns and greens, but again, I don't recall anything on the two grey primers.
