Full wave rectification with an offset p-p voltage

Well, It's AC from the wall so it's just a 60hz AC signal. What I was asking is if I could get 80v positive 20v negative/ 40v positive 60v negative/ 10 volts positive 90v negative/ etc, etc, etc, from a full wave rectifier as I am building an expensive power supply and I don't want to pay for voltage I'm not using.

Well... it occurred to me that he could adjust his original AC source using the variac, and then use full bridge rectifiers on each side...

Something like this:

VA-B=100 VAC
VC-B = 80 VAC​

Is what I'm saying viable? Or did I just put my foot in my mouth?
I don't see how that would work with a common output DC ground. :confused:
Show me how you would hook up the rectifiers to do what you want.
