Possibly, I just want to avoid the clutter. Any armour can potentially have a shield version...
One answer to these shield/armor variant overload problems would be to make Xenonauts-style shields which are basically separate, directional shield generators. XCF already has shields (of the psychic variety), directional shield scripts inherited from Piratez and X-Chronicles reportedly has even shield HP a display. Getting the three combined and making shields independent of armour would be a large step forward, IMO.
There's also the issue of making art for some sort of advanced alien alloy shield, but I imagine that's a lesser obstacle than merging all these scripts.
