I'm definitely down for a 4-pack of SA Clones! Hasbro would sell as many of these as they make. There could also be a few different kinds...
4-Pack #1: 4 white clones. This would ship the most, and would be packed with future 4-pack variations.
4-Pack #2: 1 Yellow, 3 White
4-Pack #5: 1 Red, 3 White
4-Pack #3: 2 Blue, 2 White
4-Pack #4: 2 Green, 2 White
Include the long Clonetrooper rifles, and maybe some binocs. Also, for a pack-in, Hasbro could give us accurately scaled gunship pods. Honestly, this is what they should have done for the Clone Wars line, and given us a similar 4-pack line-up for Battledroids.
