Not impossible.

I think they started in from the wrong direction, in that they tried
to make a submersable fly.

But aside from that... How big is a 'team'? How deep does it have to
dive? How fast does it have to fly? And how far?

Small team, say four men including the pilot.

One method that's worth exploring is to use the same prop for both air
& water.

You'd definitely want to do something about those air-scoops -)

Major problem would be getting an airframe to sink. Lotsa voids to
trap air going one way, water going the other.

If it didn't have to dive too deeply, say 33 feet or less, you could
probably use one of the new diesel engines for both airborne and
submerged propulsion.

Any way you hack it, it sounds like a fun project :-)
