Possible, yes. Whether it's a good idea or not is another matter.

What happens if that's a long-running data import. Job automatically kills it after 2 hours, job rolls back for the next maybe 3 hours, net result several wasted hours and a data import that needs to be rerun and when it is, it'll be killed after 2 hours, etc, etc.

Better idea, identify long running queries that cause blocking and tune them so that they aren't so long running and don't cause so much blocking. Fix the cause, don't patch the symptoms.
