I'm sure HT can do it, but we cannot "add" any new sound that are not defined. You can always swap out the wav files and change the sounds that are there, but you can't add any.
FYI there are really two forward views. One is the "default" or regular view, and the other you will get if you actually map "forward" on your stick. What I do is map a button to "forward" and then adjust my head position for that view. I generally adjust it down and back so I have a full view of the instrument panel. This view works pretty well for "checking the gauges", and is easy to use even in a fight.

A pig is a pal, who'll boost your morale, Though mountains may topple and tilt.
When they've blackballed, bamboozled, and burned you, When they've turned on you, Tory and Whig,
Though you may be thrown over by Tabby and Rover, You'll never go wrong with a pig, a pig,
You'll never go wrong with a pig!" -- Thomas Pynchon, "Gravity's Rainbow"
