You can see that the standard procedure is to keep lenses on their dedicated boards. The only problem comes when one wants to use a lens on two different cameras with different-size boards; then you need to have an adapter on one camera or remount the lens on the right size board. The former is easier by far.
If you are looking to minimize the size and weight of your kit, use small lensboards and small lenses. Many field cameras use Technika-style small lensboards these days. They are available cheaply. If your camera needs a larger board, an adapter might be in order. All my lenses are on Technika-type boards and adapt to the other cameras I have.
Personally, unless I had a lens set designed to have interchangeable cells, like a casket set or a Nikkor-T set, I'd never bother with changing cells on the same shutter. Modern lenses come with shutters; get working ones and keep lens caps on. It's dicey enough changing lenses in the field when the lenses are mounted on their boards (juggling two lenses in the wind, fog, on steep terrain, in inconvenient or even dangerous positions...) . I can't imagine fiddling with changing lens cells in the cold and juggling and storing the ones I just removed with the ones I'm about to mount. Sounds like a recipe for disaster if you ask me. Plus, this takes time, which is often at a premium when working in changing light, etc.
I'll break with some here and advise having a dedicated cable release mounted on each lens. Mounting cable releases in the field is fiddly as well, and it's all too easy to drop one down the nearest crevice or into the mud or sand or water. Transport your lenses in boxes. I make my own; stackable, but without tops so I have easy access and so there is no pressure on the release and its mount and damage is not an issue. In over 35 years working this way I've never damaged a lens from having a cable release mounted. Carry some spare releases too; they go bad at the worst possible moment
