Though starting to get irrelevant as more CUs and major banks have started issuing some form of EMV (PIN or Signature), I have updated the list with:
PenFed
USAA
AMEX Plat & Centurion
Probably not going to bother listing more CUs since CUs that contracts services with PSCU offer some form of prepaid Chip & PIN that competes with the Travelex option.
