Just my two cents, but I might go about it another way and say orbiters are a good thing.
If they are beta-orbiters secretly lusting after your gf in the hopes of one day "nice guying" into her panties (which is the most likely thing as I think we all can agree - actual male/female platonic relationships seem to be as rare as smaller government these days), they will already be pretty damn unattractive to her. You said it yourself, they have no game. That is not to say you have no use for them.
First, she can get out all her "drama" with you (i.e. the stuff you have little to no tolerance for) by yaking incessantly with the orbiters. You get peace of mind, they get to be emotional sponges for your gf (with nothing else to show for it).
Second, one potential charateristic of a more "alpha" guy is building up a following of beta guys who envy him and try to emulate him (but never quite can). I say befriend and socially dominate the orbiters as much as you can. It can both build attractiveness with your gf as you demonstrate leadership as well as get you decently loyal guy friends (albeit "beta" guys) who are still likely to be fun for a night out for a beer once in awhile.
