You've said that you've considered releasing some of the POTJ figures on blue cards. Bad choice, in my opinion.
If you want to release the Rebel Trooper or Imperial Officer again, be my guest. Just give them more accessories and new head sculpts (like white hair on the Rebel and brown on the Imperial). Go ahead with the army builders. I'm fine with those.
Release Zutton with some of the Cantina bar as a Wal-Mart exclusive. Allrighty. Make a new Eeth Koth without robes. Whatever. Just don't release old figures on new cards. I don't care if Kenner did it in the 80s.
A wonderful idea for you to rerelease these is through the Fan Club. Put them on whatever kind of card you like: it's your decision. Just don't add any new accessories (this would be a waste), or give them a number in the system.
Thank you for probably not even listening.
