You can't do much without making serious changes but redesigning the bass
cale so it's a bit less heavy at the top can also help a bit.  I don't like
dded mass at the top of the bass break, it really needs a longer extension
or added stiffness.  I haven't tried it but wonder if a small extension
ttached on the underside of the bridge pushing that small little extension
n the topside out a bit might not help the end of the bridge effect.  If
ou are taking the plate out you can simply extend it from the topside but
f not then the underside is all that's available.  
Attached is my current favorite modification for an added tenor bridge on a
teinway B (or others for that matter with low tenor problems).  It shortens
he speaking lengths enough to help with the new wound strings scaling,
oesn't change the strike point that much, keeps the new bridge in somewhat
he same proximity to the rim as the old, creates separation from the low
ass.  A bass float would be ok here too but I didn't do it on this one.
ou can see the extra extension off the top end of the bass bridge as well.

So, bottom line guys. The French piano maker Stephen Paulello "string with 
ofter steel" isn't going to do much?
I don't do any scale redesigning and thought this might be an easy fix :-(
