Historically, other big independents have dropped off the map rapidly after a period of success - late 80's CIA and early 2000's Spirit. Both cases correleted with the rise of another big competitor - Spirit & Fringe respectively.
I thought we'd removed the constraints on sorority drivers years ago, and there still seem to be to a lot of sorority shirts on pushers these days, so how to convince them that they want to run their own team rather than be someone else's women's team?
I really hope PhiDelt liked thier first buggy experience enough to return. KapSig put in an impressive appearance a couple years back & vanished. What would it take to bring them back? What other houses are left that are big enough to run a buggy program? There's probably enough potential "loaner" buggies to support one more team, so that's a barrier the BAA can help overcome. The independents aren't at full capacity, and it's far easier to grow by adding an Apex C than it is to start a whole new team without an existing organization.
