With a number of the early edition books being out on DnDClassics, have you considered the possibility of a published supplement? I have no idea of what legal issues there may be. You have quite a lot of tables, here, and a book of tables may seem like the next logical step.
On my radar but a long way off. If I do I would publish it under Labyrinth Lord which is a B/X/AD&D 1E retro-clone. I'd like to compile the random dungeon rooms and mundane items into one book once I reach a certain threshold.
My dream project is an OSR Monster book. I've been slowly commissioning art for monsters but its expensive so that may take a couple of years to complete. Plus I like full color art so that jacks up the price.
