If there's room between the pins for the strings, I'd replace #6 with #7, 
if for no other reason that I think #6 are too small for piano bridges in 
the first place. I wouldn't just drive in the next size up without reaming 
the hole. The difference between #7 and #7, or #7 and #8 is 0.010". That's 
a lot to expect an old solid cap to take without splitting.

What size drill do you use for #7, #8, #9, #10 bridge pin?
