There might be a way to do this in the way you're talking about, but I 
accomplish a similar goal (being able to easily pipe things through 
`less`) using global aliases:

alias -g L='| less'

You could use:

# H = highlight
alias -g H='| source-highlight -f esc256 -s shell'

Then to use it, the following examples would expand into your example 
commands:

ps ax | grep ssh H

or:

sa H

Not very surprising -- Tmux and Vim require pretty full control of 
terminal I/O, so piping either one through a command won't do anything 
useful.
