Dragon - What do you want them for? Keeping in mind that you only have 160x120 pixels for these, putting everyone in a helmet would make them virtually indistinguishable from one another.
I would just like to see a helmeted anis exaclty for that purpose, so I can reuse those anis in multiple places, they may differ slightly, but only slightly.
Plus, TBH, if stuff is going to get released publicly - particularly a big project like that - I'd rather it be useful for a wide range of campaigns, rather than just a niche thing like that. Sorry man.
I'd like to use them in my project, but since it's going slowly, you may release them for everyone, as I mentioned they should be very generic and diffenr mostly in background details, so everyone could adopt them.
If you decide to do it, three or two generic pilots (one of them may have some markings on helmet, indicating a commander or ace), two generic freighter pilots, three generic capships and two generic commanders and a support ship would be everything that I need. Having a technician, comm officer, marine (If you've seen Final Fantasy: The Spirits Within, you may base the it on marines from there), standard soldier and a tank driver would make the set prefect. Helmets and armour should be rather dark and don't show any skin (full pressure suits), with no insygnia.
