Roster Management Questions

Two questions for the experts:
1. Are upperclassmen less likely to happily accept a redshirt than freshmen? I am taking over a new team and have a glut of players at one position in the same class and want to know if I can redshirt a junior or senior to equal things out.
2. I know there is a penalty for cutting a scholarship player, does the same penalty apply for walkons?
