Here's my try, going a little out of the NPC, NPHC and NIC, but staying social/single-sex:

Sigma Beta Rho (NAPA/NIC)
Theta Nu Xi (NMGC)
Zeta Tau Alpha (NPC)
Omega Psi Phi (NPHC)
Delta Kappa Epsilon (NIC)
Alpha Omicron Pi (NPC)
Lambda Sigma Upsilon (NALFO/NIC)
Gamma Eta (NMGC)
Iota Phi Theta (NPHC/NIC)*
Phi Mu (NPC)
Chi Phi


That's 11 GLOs with all letters used and (I think) only Alpha, Delta, Theta*, Sigma and Phi used by more than one group, and only Phi (and maybe Sigma*) used by more than two groups.


* If Sigma Alpha Iota (NIMC/PFA) is used instead of Iota Phi Theta, then Theta would only be used once, leaving just three "repeating" letters and would reduce the use of Phi, but Sigma would be used by three groups instead of two. But naraht specified "social" GLOs, and I'm not sure whether SAI considers itself social, professional or something in between.
