Since AMSAT-DL and AMSAT-NA both require funding from outside the amateur
radio community, are going after different sources of funding, and neither
can predict when they will get that funding, having two efforts would seem
to double the opportunity for a non-LEO satellite.
I don't think that the risk decreases with P3E. 50% of P3 satellites were
lost due to failures of engines in the launch vehicle or in the satellite.
I don't see how having a linear transponder in a geostationary orbit versus
a Molniya orbit makes it an appliance satellite. The antennas and
transceivers on ground are the same in either case.
