It seems to me, despite talk of change, LW is staying essentially the same... and thereby struggling at an accelerating rate to be a place for useful content.

My current modus operandi for LW is to use the LW favorite I have in place to (1) Check SSC and the other "Rationality Blogs" on the side bar, and then (2) peruse discussion (and sometimes comment) if there isn't a new post at SSC, et al that commands my attention. I wonder if other LWers do the same? I wonder what percentage of LW traffic is "secondary" in a way similar to what I've described?

I like your suggestion because it is a radical change that might work. And it's bad to do nothing if what you are doing seems to be on a trajectory of death.

At some point, during a "how can we make LW better" post on here, I mentioned making LW a de facto "hub" for the rationality blogosphere since it's increasingly not anything else. I'm now re-saying that and seconding your idea. There could still be original content... but there is nowhere close to enough original content coming in right now to justify LW as a standalone site.
