TL;DW - simply change session for your triggering character (if i'm right. might need all characters on grid to change session...and it might not even require you to avoid getting aggro'd on by the spawn you didn't like)
followup: looks like i'm right. as long as you warp off before they aggro on you it'll trigger the respawn (just change session by docking your spawning character) mechanic.
