Sorry if this was already suggested, but I would like to see a mission that takes place in an underwater temple. This would mean swimming could be made use of to traverse the place (potentially with some way to swim a little faster) as well as some plot-based reason for actually removing the suit techs. This would mean that being underwater is something dangerous as people would have to find air pockets to stay alive (or potentially pull a Sonic the Hedgehog style and add in some air bubbles underwater to help breathe) The boss could be a giant squid monster or something. This could actually be put into the list of mission but instead as a side thing. The lack of breath suit techs could be part of the challenge as well as being given armour to help move through the water faster and that upon completion of the quest would allow the person to keep their fancy new swimwear.
