Excuse me, but aren't you making the same mistake as Lomo hipsters here, but in reverse? They shoot a certain type of film not because they're familiar with it or because it's right for their work, but because it's "cool" to do so. YOU are refusing to shoot a certain type of film, even though it might fit perfectly for your application, because shooting the film offends YOUR sense of what is "cool" (for you, not being hipster = cool).
If Lomography style film is what will get you to where you want to be -- and I think it's a good bet it will -- you should keep on doing what you've been doing: ignore the hipsters and use the best film for your job, reguardless of what they're doing.
I, personally, would not confuse interesting, weirdly-colored "lomo-esque" images of cosplay characters with hipster lomo-esque shots of cats sniffing at the lens. Remember that composition and content are much more important to your artistic message (or the hipsters' lack of a message) then whatever kind of film or camera you're using. I'd bet that for every "eww he's just a lomographer" comment you'd over hear, you'd find TEN people saying "see! THAT is the sort of thing Lomography makes interesting/appealing."
