Park, no.
No, no and no. If you have a problem with that, Starstryker can find itself outed as a front for the Guild, and Gilliad can take an anal intrusion from Beff Pike. You may love your little subfaction just like you love having all of your pudgy little fingers in as many factions as possible, but keep something in mind; the Guild is mine and if you want to fuck with that, I will fuck you up.
You do not have subfaction status because I never granted it to you, In or Out of character. In fact, the only connection that exists between Guild and your little wet-dream is a haphazard connection that, at best, is tenious. So, if you're seriously interested in having your own control over your own group, take your Corporation and stuff it.
Sounds harsh, huh? But I can't help thinking of that old BDE fuck up.
