I don’t know in Chat someone came up with the “curse of the 7th episode”–that Ruby and Graham both had centrics in that spot and are now more or less off the show. So I don’t want Neal’s centric to fall in 307!
That aside, its not a reason it couldn’t happen, or that they couldn’t actually kill him off, but I would not want them to do that. I feel we’ve already had the impact on everyone and it would be much more interesting to explore various things with him in the mix.
