m43 Underwater

Regarding macro, I got a weird idea: on my old (and now sold) Nikon D7k, I used a 2.8/105mm micro nikkor - which is tack sharp. My heart would bleed seeing this wonderful piece of optics going away... Is it possible to use it adapted, underwater with the e-Pl5 (or any other mft bodies)? Do uw housings allow for adapted, manual lenses? (=big diameter port w. manual focusing gear)
