Will the gimbals be able to be taken off and the hardpoint become an S2 fixed, like other ships, or will there be some Vanduul caveat that doesn't let you alter the weapons? Will it be able to take other human weapons, or will it have Vanduul specific weapons? If Vanduul weapons only, then how are they expected to preform when compared to other s1/s2 weapons?

Long term you'll be able to mix/match race-specific weaponry provided you have an appropriate cross-species mount. For example you could take your S2 Vanduul weapons and with a appropriate mount attach them to any UEE ship. The specific penalties (if any beyond requiring another mount in your inventory) are still to be decided.
