It makes perfect sense. Clearly not all HOF'ers are equal and they can easily be split up into further categories.
If you don't want everyone to be in one level, don't support "lesser" people for the Hall
That's the whole point in being a "big Hall" or "small Hall" guy. You have one level that's the Hall of Fame, and everyone else stays in the museum.
No, it's not the whole point at all. No one, regardless of how small a hall guy they are pretends like all the players in the hall or in their hypothetical hall are on the same level.
