Extra module for propellers or an underwater equivalent of a 3303 jet engine - splattering plasma in a high pressure liquid might give some unwanted extra boost but we still need to move at an acceptable speed. Also a sonar...or an upgraded planetary landing module.
Or a submersible SRV.
To be frank I'm not at the edge of my seat regarding WW. It will either be a boring, black, featureless nothing that is basically a darker version of regular planets where we can float around or a lush, living amazing sci fi dream...and that's not very realistic at this point IMO. In other words - dead and boring or alive and we already have ELW/AW.
