The more I think about it the more I think two 4-packs of main characters would be ideal... both for new fans who missed the old releases or old fans wanting to upgrade/army build their crews. These would include alternate pieces to make Bones in his short-sleeve shirt and plenty of phasers, communicators and tricorders.
-Kirk (yellow shirt)/Bones/Uhura/Sulu
-Kirk (green shirt)/Spock/Scotty/Checkov
Then they could release one series of 4 two-packs with other characters like:
-Yeoman Rand/space suit from "Tholian Web" with alt. heads
-a Romulan and Klingon with alt. faces/hair for army building
- yellow dress crew member/sculpted-face Gorn
-Nurse Chapel/Salt Vampire
Maybe even do an exclusive set to TRU with the Kirk set mentioned above along with a couple exclusive sets such as:
-Andorian/Horta
- transporter/engineering tech guy in the baggy red jumpsuit/Mugatu
That done, move on to other series.
