I can't say for sure, but I don't like the idea. It seems to me that
putting four or five times the normal bearing load on the bridge edge, at
an exaggerated deflection angle, has got to do damage to the bridge top at
precisely the spot it can least afford to have damage done. I find that
settling coils, squeezing loops, and prying or pulling strings to
straighten them up around bearing points does a fine job of stabilization.
I suspect that is what the roller is doing anyway, rather than taking
stretch out of the string, only at more risk to the bridge. 

Anyway, that's my call.
