Hey, Brian, Neither I nor you are going to like what I'm about to say (but I think it's where you're headed). :)
We have an equivalent use case, where we're trying to keep long work off of a certain number of nodes. Since we already have used "long" as a QoS name, to keep from overloading "long," we have had to establish a "notshort" feature on all the nodes where we want to allow jobs longer than N minutes to run. We use job_submit.lua to detect job duration, and set the notshort feature as appropriate. No user action required.
