Reading your posts - I think you should focus on what you want to shoot and what lenses will work best. Just know if you shoot wide angle and you want a lens with some zoom range the port will be bigger, if that is that a deal breaker - then stay with the Oly 8mm and small port.
So here is my experience from using Olympus Pens w/Olympus housing and now I have Nauticam with OMD1.
I have the panasonic 8mm and love the fisheye and small dome port. Great for traveling but, like you said, it is only 8mm - no zooming.
I have the 9-18 but rarely used as it doesn't have the sharpness I want. I got this lens when first starting to shooting with Olympus Pens, it was ok then but there are better options now. Mine is gathering dust - if you really want a 9-18 - would love to trade you for the Oly 8mm and some extra $$(the Oly 8mm was not out when I bought the pany).
I have the 12-40 Pro with a Zen dome, which I really love underwater when I am not going to shoot only macro - but the dome is big and you have to put the lens 12-40 on after the camera is in the housing - to big (for me) to travel with unless I am only going to shoot big stuff, but locally I love to use it. This dome works with 7-14,9-18 and Oly 8mm.
I have an 12-50 lens I got with my first OMD camera, and if I want the whole range I can use this lens, but I have the port that allows for switching to macro. This lens is not as sharp as the 12-40 but you get the extra range. I don't use this much unless I travel and think I might want a WA lens for a day.
When traveling I will take my 60mm for macro, and my 12-50 for wide angle (they use the same port) and if I have room, the 8mm and dome (just because it's so small). If I'm shooting really big stuff (mantas, sharks) I would use the 12-40, but I wouldn't be taking most of my other ports/lens. I have 2 strobes, focus light, housing, arms, batteries, in addition to camera and housing and the above. For 1 person this gets to be a lot. So depending where I travel, I try and pack for the critters I expect to photograph.
