No problem.  I enjoy coming up with stuff like this.
As an addendum, you could change the macro to:

#macro RecAreaLight(SIZ,GSIZ,RADIUS,FALLOFF)
  #local
ASIZ=SIZ*(tan(radians(FALLOFF))-tan(radians(RADIUS)))/(tan(radians(FALLOFF))+tan(radians(RADIUS)));
  #local DIST=(SIZ.x+ASIZ.x)/(2*tan(radians(FALLOFF)));
  area_light
  <ASIZ.x, 0, 0> <0, 0, ASIZ.y>
  GSIZ.x,GSIZ.y
  translate y*DIST
  projected_through{box{-<SIZ.x,0,SIZ.y>/2,<SIZ.x,0,SIZ.y>/2}}
#end


I.e. remove the jitter, adaptive, etc. from the macro itself.  That way you
can control it in the light_source instead.  Just add the jitter, adaptive
'n', orient and/or circular keywords as needed to each light_source after
invoking the macro.
