Can anything be done with a '"Teflon Steinway", short of action replacement ?

[gordon stelter]

Dear Everyone,
    I play almost daily now on a 70's "L" in the lobby
of a  fancy hotel, and the "Teflon Action" is killing
me! Too heavy, clumsy feeling, uneven, etc.. I have
replaced a couple of these, but wonder what
alternative steps might help this thing, in case the
management doesn't want to spring for a full
replacement.
 
    Thanks!
    G
