That's fine -- it's much better than nothing

You'd be releasing the data under CC-BY-SA and ODbL. If you are acting
on behalf of the copyright owner, then you don't need to add any further
documentation -- simply uploading the data is enough to show you agree
to the licences.

A separate account for the traces may well be a good idea. As for
aggregating the traces, I don't see any benefit to OSM of doing that,
especially if it involves you doing more work. If it's the effort of
uploading multiple traces that worries you, there's an Alpha-quality
Java utility that I'm happy to help you to use:

Yes. More source data is always good, especially if it's based on real
movements.
