Did JRRT encourage new ME stories?

I can see someone with a knowledge of M-e equal to Tolkien's coming along one day. I can also see someone with his genius for storytelling coming along one day. What I can't see is that they will ever be the same person.....

It strikes me that a true creative genius would want to create their own world, not simply take up someone else's.

That said, Tolkien in his Will authorised Christopher to continue his work

’Upon Trust to allow my son Christopher full access to the same in order that he may act as my Literary Executor with full power to publish edit alter rewrite or complete any work of mine which may be unpublished at my death or to destroy the whole or any part or parts of any such unpublished works as he in his absolute discretion may think fit and subject thereto’

So its entirely possible that Christopher will do the same. In other words, a continuation or addition to the mythology is not entirely out of the question - JRRT actually gave Christopher the right to do just that. That Christopher did so little 'completing'/re-writing is a testament either to his respect for his father's work - or an acknowledgement that he was not up to doing more than he has.

Either way, Tolkien himself clearly was not opposed to Christopher adding to the Legendarium.
