It sounds that a token bucket filter (TBF) with low rate and intermediate
burst level per connection is the thing you need. But I'm afraid if cou
attach a TBF qdisc to a class, it arranges the queueing for all the
packets in that class, and it won't differentiate between the connections.

I'm not sure about this, someone who knows better is invited to correct
me.

Maybe you can achieve a comparable effect splitting the traffic depending
on static TCP ports first, and fine tune the setup later ..
