The best way would be to make a custom OpFor and add a pilot there – that way you have full control of everything about them.
We have a “good ideas we don’t want to lose” ticket sitting in the backlog along the lines of your idea – getting both a pilot portrait and bark lines from backers as an additional survey – but so far haven’t had the time to put it together and can’t say for sure we ever will. It was a significant time sink to even just scan all the callsigns to vet them (removing direct references to politicians/other IP), so barks would be a significant job to do the same. Even though I suppose it’s likely we’d get way fewer submissions…
