You're quite right that the linearity needs to be good and at high gain,
however I'd be inclined to use a passive 20dB per step attenuator on the front
to maintain a good overload margin.

How about 32bit with 384kHz sampling? Boxes like
these are starting to spring
up.

That box is output only. That seems to be quite common.... that is there
is a consummer interest for output boxes but only niche interest for input
or i/o boxes. Input boxes of good quality will cost more as it is easy to
build the low gain output analog circuitry but much harder to build high
gain, high quality, linear, controlable (with accuracy) input circuitry.
For a scope, knowing the exact level at each gain position is pretty
important.
