I remember reading Inquisition War, where there was a Harlequin warband consisting of 1-2 harlequins and a Death Jester.
I was thinking of having a warband of a "troupe leader", a death jester and mabe a shadowseer, running around looking for some lost eldar artefact.
Any thoughts and ideas on harlequins in =][=? What kind of rules would you suggest?
(I'd say crits from kisses would auto-cripple the location)
There was some discussion on this subject a while ago;

Not sure if that covers everything you need, but it should do as a start...
