Possible and probably not too hard. IIRC I started doing it a good while ago but didn't get it finished.
I would make it so that you can either do this: $ tmux neww "my command" Or $ tmux neww -- my command Which means you don't have any ambiguity. I think you could either try to make it be detected early in command parsing and presented to the command as a single string (like now), or alter each command individually (new, splitw, neww maybe a couple more).
