Now how do we structure the current BCSequenceXXX classes? Do we keep
the BCSequence/BCAbstractSequence pseudo class-cluster, or are we
changing it to a superclass and three regular subclasses, with as musch
as code in the superclass? I would vote for the latter, mainly because
the former seems to be confusing in use.

You mean multiple inheritance? No I don't think that is possible in
