Schools With the Same Chapters?

[angels&angles]

I was thinking about some of the NPC detectives on here figuring out PNMs' schools (for fun/profit), and what a big help it must be when they list off the actual chapters at that school. Which brought me to the question: Are there any two (or more) schools that have the exact same sororities, now or in antiquity?

Hypothetical Examples:
Both Southern Private College and Northeastern State currently have the same 4 chapters: Gamma Phi, Alpha Sig, Phi Sig, and Alpha Phi.

In 1954 Liberal U had 6 chapters: DG, DZ, KD, SDT, ZTA, and AGD. In 1978, Tech College had the same chapters.

Confining the parameters to after all 26 sororities joined the NPC, and to schools with more than one NPC chapter, does this exist? (I tried going through Irishpipes' thread, but it made my head hurt. Someone else may have a better method/database/headache meds).
