Yes: you don't share drawing code between variants, you only share
parameters. But if you have any suggestions on how to do it, I'll think
about them.

Good idea, this syntax is quick and light. But I made the choice of very
explicit (and rather long...) parameter names and I'd like to stick to that
policy.

The real point is that I don't know... Since the begining of the rewriting
of pst-circ2, I don't know what to do with multipoles. So, if you have
suggestions on how to implement it (no too far from the \DeclareNewDipole
structure, for consistency), don't hesitate.

I'll have a look at your problem as soon as I get some time!

Thanks for you interest.
