A sniper would work amazingly well with Gisela, actually! She's all about scanning the area to locate enemies and assess their capabilities, then shutting down their sensors/communications so they can't locate the squad or coordinate movements against them, so she could serve as a spotter for a dedicated sniper unit. If the combat support then had more of a "suppressing fire" focus, or a close-quarters combat specialization in addition to repair capabilities, that would round out to a really versatile and dangerous team.
