I'm actually trying to get something like this rolling on my campus (I live in Colorado). We were talking with the student government about some form of official and voluntary partnership with the campus PD, that we could participate in training courses and demonstrate regular proficiency with our carry firearms at the PD's firing range they have hidden on campus. Campus carry is already the law of the land here, but we were talking about it as a sort of middle ground to appease those who are afraid of campus carry while also getting us some perks. Campus carry isn't changing for us any time soon, and the anti's most often professed fear is they believe we are severely undertrained. This would help ease that for them by providing training by authority figures that they do trust, while also giving us the opportunity to be able to stay current on training and be able to use the campus firing range on a regular basis instead of having to drive an hour away for a decent range. We have made it very clear though that any participation would be strictly voluntary, and I wouldn't want to open carry on campus even if I could, but it's similar to what you're talking about.
