There's a good reason I suggested RM furnaces over DM Pedestals. While you may get trivially denser storage with DM Pedestals, nearly all servers ban them thanks to their exploitability. On the other hand, most servers by now have figured how to disable RM Furnace's ability to dupe items with Tekkit Restrict so allow the crafting of those.

If you're just using it for single player though, it's fine.
