There is ultimately no saving these old corporate controlled properties, until at least they go public domain. They are gone to the Shadow. They are Osgiliath and Minas Ithil, when you've got to save Minas Tirith first.
The only sensible thing you can realistically do is support new, talented authors who have things together, and who are making something decent. None of the energy spent on trying to unpoz Star Wars or LotR will produce anything, but supporting young guys writing decent genre stuff is worth your time. Not because everything they do will be good, but because they are creating an alternative ecosystem where good things can emerge and not just get killed off by someone who just rejects everything appealing to men.
Cirsova is a fantasy magazine whose owners have their heads screwed on right, and while it is kinda hit and miss, you can get some good stuff from them. DMR Books is releasing short story compilations that always have a few really nice ones, and they are low key based too. You aren't getting Tolkien or Howard yet, but when someone like that comes along, he will have a home and a buying public. Be that buying public, and the talent will emerge.
