I would indeed, xamboldt
However the medium of email text limits me to mere descriptions of what I did to the Wbug design. 
Thus I will describe them here. But i fully realize that, in the rough and dusty streets of DIY, descriptions talk the talk, but  schematics walk the walk.
Unfortunately I'm not well set-up to capture images (I'm kinda old fashioned) and my schems are hand-drawn thus requiring a scanner that i don't have. Please see my comments after the list of mutations.

(it will help the reader immensely to have a copy of the #3 standard Wbug handy for reference) 
I listed them in order of my own preference.

1-addition of a switch that switches-in other values for caps C6 & C7 independently.
2-a separate control circuit (CV/Knob whatever) for VC1 (VTL5C3/2 vactrol) 
3-enhanced and independent control of the U5 (555 astable) clock circuit which included it's own "private" S/H-controlled rate that samples the same buffered sawtooth as U1 (LF398) does
4-a built-in frquency divider on the woggled-tone output that 'knocks' a CV-controlled resonant circuit. This produces odd rhythmic patterns that bear a relationship to the Wbug's output. (I called this sidecar circuit... a 'stinkbug')

fair warning: I'm a brazen hacker. So a good portion of these mods defile the elegance of the design. (type-A chefs beware! I'm a hash-slinging short order cook!)

I have considered asking Mike Fisher about the possibility of adding a sub-topic discussion page for folks willing to rip their Wiard warranties into little pieces (like i did) and modify Wiard circuits.  A sort of 'Mutant Wiard DIY' group but as there are very august and well-developed synth DIY groups out there, it might be narrowcasting a bit too much. but i'm delayed in bringing it up because my real-life circumstances are in frog-in-a-blender-mode right now and i don't have time to instigate or contribute.
But-
If there is any generous soul with time to spare and a scanner that can handle 11"x14" pages I'll be happy to snail-mail some schematics related to the above mods for posting on this site.
(provided the designer promises not to sue me)
