Yes, I've read them completely, and spent many hours digging through
the BBv2 source code to extend it. I implemented the original
BoostBook toolchain in BBv2 and more recently the MPI toolset. I'm
not making suggestions as some naive user who took one look at BBv2
and threw up his hands to say "use my pet project."

The answer to both is "many, not all." Does Boost.Build support all
features of CMake? No. There's a big overlap in the feature sets:
CMake is missing some that the current Boost.Build has, and
Boost.Build is missing some that the current CMake has.

Then go for it. Time will tell whether this rewrite will be as easy
as you think and provides the benefits you expect.
