It works, and we actually have the boxes set up this way...
but you miss one thing - unless the static route has a greater metric than
the metric of RIP learned route ComOS will prefer the former
in all boxes but the one the remote net is actually connected to.

You can't assign greater metric to static routes - ComOS distributes
the static routes with the configured metric values, so they will get
(from the box of actual connection) into the other boxes with
metric+1 and won't override their static (non-functional) routes.

The net result is that everything works except the remote network
is not accessible from all the boxes (but one) with static route to
it configured. And of course all the networks beyond these boxes
can't reach the network (and vice versa).

You may consider it "works well" - I don't.

I'm waiting for Livingston to answer this particular question.
