Is this a bootable offense?

Shoulda went for the hat trick.

Relog onto another toon, join party.

Get into the quest. Head right back out into the desert. Re-enter. Go find somewhere in quest to die. Res out, leave party.

Or am I being too mean?

well. there is joking around like what the OP did, then theres being an A$$ like what your suggesting.
Pulling a stunt like what your suggesting would get you squelched, and your guild blacklisted by most.
