Wargentin-
Yes, a VERY detailed post! I may be a Denkhead, but i still appreciate hearing about other types/variations of gear... maybe that makes me a "gearhead" first? 
I'm curious tho- if a person were willing to create a second (*slightly* shorter) set of truss-poles for BVer mode that would accomodate focus using the OTHER glasspath correctors, the first few you mentioned- would there be an optical benefit in doing so?
I know, it'd make the Dob pretty much a "dedicated" BVer scope for that session, perhaps accompanied by a mono-scope set up adjacent? But if it would alleviate the need for the "fix" you've described, would the image quality deriving therefrom be an attractive option?
Also, at what F# would you estimate that the abberations you've described would be lessened to such a degree that *you* would consider them negligent. I know, each observer might call that at different points- yet for continuity of thot, i'm curious where *you* would mark it.
Like MANY things Dob, we all have criteria that we attempt to balance for our own, personal pursuit of the "ideal" scope; The primary's F-ratio is just ONE design-point in each of our equations, so if it were dialed up a skosh, other attributes could be "gained"- which might include one's BVer system!
Regards,
 mike b
