As long as the player skills are not shown, I like the idea. It's harmless fun like the All-star game is anyway, so why not.
Another option would be to let all the managers in the conference set the tactics individually, i.e. effectively vote which tactics the team would use (the settings should perhaps be made in order of preference). This way it could potentially be a community project and something to discuss in the league forum, thus getting people more interested in the All-Star game. Some silly tiebreaker rules would need to be implemented, though.
