There is very little downside in attempting to reach out to people you don’t know, but respect. At worst, they will not respond or respond and say no to your request, which is the same as if you had never reached out in the first place. However, the potential upside is huge. You could get your request, get something better than you requested, or even forge a new relationship.
Assuming the time commitment in doing the outreach isn’t too high, you have very little to lose.
