A little off topic as to bending the spring but does lighten the spring. I'm not recommending or advocating doing it but I've seen it done. By lightly grinding on a belt sander, going slow not to overheat but to narrow the spring width. I guess maybe the same thing might be achieved by thinning the spring thickness rather than the width but I've not seen that done. I'm not an expert so regardless, I think bending would be better and with the availability of relatively inexpensive springs, a replacement would probably be better still.
