Sure it's possible, but it would need some work, and I suspect
there are easier ways to speed it up for now.

It's worse than that, as the daemon effectively caches a list of
traces which need doing at the moment.

The other issue with doing more that one at once is the resource
requirements in terms of CPU time, disk I/O, memory, etc.
