The thing about a Holo Boothby is you are talking about likeness rights. And then presenting him in a positive light.
As much as I like the character, I think it would be better if we had a new character that acted as Boothby's apprentice (passing on the torch). Could be a former Starfleet Academy student who got attached to the grounds keeper and took up the reigns when he passed on.
NO to ARC!
