I say include Crusher's coat, B'Elana's Coat, Picard's Coat variant, The excursion jacket from WoK and Scotty's jacket from Star Trek IV into a Jacket and Coats pack.
I do love the idea of future "packs" being a set of existing items modded along a theme.
For example, the vest pack, with Picard/Sisko style vest (First Contact minus jacket), Torres vest (the vest with no undershirt look), Kirk Generations vest, and Scotty "Relics"/STV vest.
Or the "Alternate Universe" pack with Admiral Picard's Future Imperfect look, Yesterday's Enterprise uniforms, Parallels combadge... and maybe an inverted Wrath of Khan jacket with a Terran Empire badge we can wear on any uniform.
Heck, here's a simple one: DS9-inspired "Klingon Infiltration". Unlocks a Klingon head with Klingon options for all races and the most basic Klingon uniform as a costume set; not like Feds can't already do that with exchange officers and/or custom aliens and/or Fed Klingons.
You could likewise do the same for Klingons with a "Human Infiltration" set that comes with formal wear and a human-style head unlocked for all races, Arn Darvin/Barry Waddle style.
