Just be glad that you have all that different items. Keeping an inline around is not a bad thing. And believe me, you can accumulate as much junk with Tradtional rifles if you like to experiment. I would just had an inline box and a traditional box. Or build some shelves like you mentioned. I have a room and a half dedicated to my muzzleloaders and am always finding myself running out of space. I could not give up any of my rifles.
