No, but I have two ideas:

 1. If you want samples, just take all the November tarballs available
on CollecTor.  That reduces the total data to around 1/12.  Of course,
if size doesn't matter, just take all the tarballs available on CollecTor.

 2. Help us extend metrics-lib to not only parse descriptors but to
also generate and format descriptors.  I could imagine adding a
DescriptorGenerator that produces Descriptor subtypes with freshly
generated crypto keys, possibly with an option to pass a random seed
for extra reproducibility.  And we could add a DescriptorFormatter
that converts Descriptor subtype instances.  That would be very useful
for writing unit tests in other applications that use metrics-lib,
including Onionoo.  However, this is a major effort, with nobody being
available to spend that effort right now.

All the best,
Karsten
