Did JRRT encourage new ME stories?

If I am not mistaken Davem did not Tolkien write to Christopher almost pleading with him to try his hand at writing, and if he could not find his style why not try his (fathers) own. I have always looked at this as Tolkien wanting Christopher to expand on his own writings, knowing in some way that the vast legacy he would leave behind was unpublished. Imagine working on something that took most of your life and seeing it rot in the garage, I think Tolkien may well have had the foresight to involve Christopher in his work, however it took two lifetimes to achieve what we all love today, and left no time for Christopher to find his feet.
