I think the hard part to overcome is the negative publicity and attitudes so many vertical bow shooters that depend on anything but facts for their opinions hang on the crossbow hunter.
They're like, "So, you killed it with a crossbow, it's cheating and you should be ashamed - not proud!"
Give most of them a crossbow, send them hunting, and they soon realize it's still just archery.
Every legal/ethical kill with any bow is a reason to celebrate!!!!!!!!!!!!
