Fn 509 grip chop

I've been wanting to chop a G17 frame to make a 19L but have this 509 sitting around. So out of curiousity, would it be possible to chop the 509 down to accept FNS9-C mags? I'm under the impression that FNS mags will fit in the 509 with the 509 baseplate. Mainly posting out of curiousity for shiggles, but kind of actually considering it if it can be done. Any help/leads/bad advice/insults are accepted.
