With the new /invite could one be writen to invite whomever sends a tell then check to see if they /accept group, then CotH them and remove them from group. IE AFK raid/guild coth mage(s) for KT, trials etc.

I have played with this idea abit with not alot of luck other than coth'ing group members, bots etc on command.

Thanks in advance if possible

Yes you can. I have my mage configured to use call of the hero via request using autobot, and he also accepts group invites from anyone on his master list. Of course he also nukes, debuffs, and summons his pet, plus weapons for it and anyone else who asks. He also keeps up his self buffs, buffs others on request, and even begs for buffs for him and his pet if you tell him to. On top of that he accepts rez if he dies and loots his corpse, and will ninjaloot npc corpses if you tell him to.
