That's already implemented - see the options described in uct/uct.c
under the heading "Node value result scaling".
This even is one of the things that happens when you enable
maximize_score, but the score takes just (at most) 0.01 of the value,
where 0.99 is depending on win/loss. You might try to see what happens
if, in addition to maximize_score, you also pass
val_scale=0.1
(instead of the default 0.01) or even larger value. Not sure what
effect on strength it might have.
