Yes, but it will get wet.
The lenses are designed to be mounted/unmounted underwater.

Thank you, I would hate to mess it up if it were to be dry mounted only.....
As a side note, I always mount a wet lens underwater so that there is no air between the camera housing and the wet mount lens. This prevents any kind of goofy bubbles in your shot and in the outside chance that there is an air tight seal, it will keep the pressures equalized and make removal of the lens possible.

Hopefully it's not stating the obvious too much, but if you plan to remove and replace the lens underwater, then an inon lens holder will also be really useful. Lens holders (sometimes called lens caddies) attach to your strobe arm and well, hold your lens when your not using it. I think 10bar make these as well, and no doubt Ultralight too.
OP
Yes, I saw the caddy for the lens online. A good investment so one does not drop the lens in to the abyss.

I have the Inon ULC-100 and use an INON lens caddy as well. But I also use a piece of heavy monofilament line as a lanyard around the lens. One end has a large loop that goes around the lens barrel with enough stack to allow the lens to rotate when attaching and a second, smaller loop that I attach to the frame of the base holding the housing. Both loops are secured with compressible aluminum cable clamps. Just in case I ever drop the lens while attaching or removing it.
Another suggestion: Whenever attaching or removing the WA lens, orient the housing so the lens faces UP. That way gravity holds it against the housing until you're finished. This last point is especially important when you're installing a lens that you can't physically attach with a lanyard such as the 67 mm macro lens.
Also orient your lens caddies (I use two, one for WA and one for macro), so gravity will hold the lens on the caddy while you're screwing it on/off. Back off the threads, i.e., screw CCW, until you feel the threads drop, then screw CW. Reduces the chance of cross-threading the lens. With practice, you can feel the threads drop. Practice above water first.
