Our previous neighbour had a static caravan in Bewdley that had to be
fitted with some sort of cantilever to allow it to float *when* it
flooded.

As long as you can allow for all the vans (on say a park) to float
whilst maintaining their positions sufficiently to avoid contact with
each other and against any debris that may be swept towards them, it
sounds like a good plan.

The floor height of most static vans are about the depth of a pontoon
in any case so it shouldn't affect much if they were pushed into a
'Duck' like thing and the front sealed up. ;-)

I'm guessing many d-i-y houseboats are formed that way. ;-)
