If one of the big problems with making the jump from the J to the SHL is feeling unable to compete with 600-800 TPE, why not force SHL teams to run 4 lines? Every SHL team whose tactics I've looked at only dresses 15 skaters, and adding 3 forwards to each team (with a minimum ice time requirement like the J has) might not be a massive improvement, but it provides a landing spot for the high earners to feel useful without taking a roster spot from a higher TPE player (or forcing a GM to sacrifice a more competitive lineup with a high TPE IA just to call someone up "early").
