I agree with most of your proposition, but going a bit off topic here, the removal of "captain TP" between outpost would not add anything.
Everyone would just travel between outposts in basic cutter and that adds nothing new to OW content compared to what we have now.
No ship TP is enough as it is.
I don't even see the point of no TP from FT, considering you'd still have to sail your ships and repairs in there anyway. As a PVP Global France player, stuck in the corner of the map, I would be more involved in foreign waters if it meant I wasn't locked in there. The idea of sailing back to my main area for whatever reason in a basic cutter just for the sake of it makes me puke.
