These TRU four packs have great possibilities. However, simply rereleasing old figures with little or no new stuff in there isn't one of them. Here are some ideas for some more, all of which would fly off the shelves and wouldn't cost too much to make:
*Trade Federation Cruiser - Obi-Wan Kenobi (POTJ Jedi head with EI Naboo body), Holographic Darth Sidious (same as EI), TC-14 Protocol Droid (same as EI), Destroyer Droid (same as Clone Wars, but different arms), shield generator
*Naboo Royalty - Battle Queen Amidala with Ascension Gun (same as EI), Sio Bibble (same as EI), R2-B1 Astromech Droid (same as EI), Naboo Royal Security (same as EI), light-up laser cannon (the deluxe thing from EI)
*Geonosis Battle - Anakin Skywalker (Secret Ceremony body, Hangar Duel right arm), Battle Droid (Arena Battle - red version), Obi-Wan Kenobi (Nightclub version, new arm, new cloth skirt), Flying Geonosian Warrior (deluxe version, but repainted better), arena column (from Arena playset)
*Battle of Muunilinst - Clone Armor Obi-Wan Kenobi (Obi-Wan head on SA clone body, new outer and inner cape), two super articulated Clone Troopers, Red ARC Trooper (with correct guns), speeder bike
*Rescue on Ilum - Yoda (Chian 2-pack version, with brown cloak), Padmé Amidala (Droid Factory chase body, new head and cape), C-3PO (gray repaint of Millennium Minted Coin version, not vac-metal), Count Dooku holograph (clear blue sculpt of Screen Scene figure, new arm), chameleon droid
*Tantive IV Invasion - Rebel Trooper (same as Saga - use any head), Stormtrooper (same as COMMTech, with different small blaster), R4-M9 with Mouse Droid (same as POTJ version), Princess Leia Organa (same as COMMTech version)
I'll add more later.
