Again, sorry to get meta, but I don't think this is the kind of thing that can work in practice. Not with the numbers so firmly on the goblins' side, and certainly not under a turn-based combat system that forces you to choose between fighting or moving fast. Even the slightest amount of resistance would slow down the "recovery team" long enough for them to get surrounded. You're new to this game, rax, but we've had plenty of fights where we were outnumbered, and believe me when I say that in such a fight, the party's mobility is the first casualty.
If we try parlay first, we still leave open the possibility of resorting to violence instead. Whereas using violence right away would reduce to zero our chances of talking things out.
