This thread is an interesting deadlock between two parties:
Users who think LFS is a really good idea and want to see it thrive
versus Developers who have worked on LFS as it exists right now and
been frustrated/burned/otherwise made unwilling to continue working on

I fall into the first camp and think LFS would be great in FUSE:

However, the sheer number and caliber of developers who fall into the
second camp says a lot about the current implementation of LFS, so
maybe some middle ground would be a good place start.

I'll WAG a suggestion, but my own abilities really limit the amount of
weight I can put behind it:
Start an LFS-lite filesystem as a new project to help solve the
problems expressed by frustrated developers and targets the main ideas
keeping the LFS user community passionate about defending it.  (the
90% solution?)
