the step-down fixes have been passed and not follow the GS unless it
is consistent with these restrictions. So, it is ok to fly the
glideslope, but you must perform these checks as the approach
progresses.

Seems like a good double check yet lets me keep the stablized
approach. The other issues of MDA vs DA and the possible advantage of
entering VFR earlier if you dive & drive are noted. Thanks to everyone
who responded.

Google for "constant angle non-precision approach" for lots of
discussion about the pros and cons.
