That's a scaling issue, not a bridge issue. If you don't 
change the length progressions across the struts, and get the 
break% up in the low tenor, yes - only not as much. As I said, 
this is expectation only. I haven't put an epoxy laminated 
veneer cap on an original bridge and soundboard.

No guesstimate. Try it and find your own numbers.

I haven't found the much discussed unison smear to be as 
dependable as claims indicate, so again, try it and find out 
for yourself.
