That's what I would do for a tweeter attenuator switch, exactly. I think I'd probably use a switched 0.22uF capacitor placed across a 0.1uF when the switch is closed. That way the circuit has 0.1uF when the switch is open and 0.33uF when closed. The tweeter will be attenuated 3dB when the switch is closed (0.33uF) and it will be attenuated 6dB when the switch is open (0.1uF).
what sort of caps do I use? the normal caps I can get are much bigger values. Are 100v greencaps bipolar? I can also get 630v metalised poly in the right values, are they bipolar do you think, or should I ask the dealer?

Use polypropylene film capacitors from your favorite vendor where possible. Get caps with foil conductors for small values, metalized film for larger values. You can find them from Solen, Dayton and just about every manufacturer of "audiophile" parts.
