Cantina Currency Advice

Looking for advice on what to do with my cantina currency. The only cantina toons I dont have at 7* are JKG, mob enforcer, stormtrooper, jawa scavenger, and first order officer.

None of these toons really fit into any of my squads and they dont seem particularly useful so im wondering if I should stockpile my currency in case someone else gets added.

Any advice is appreciated. Thanks!
