Torching the windrower

Buddy has a windrower that he bought with the conditioner rolls removed. He priced out a set if used rolls for it and it was half as much as the machine was worth. The conditioners are only about 5 ft Max and thus the windrows are 5 ft wide on a 14ft cut. Has anybody tried making the opening wider to say 8 or 9 ft? I'm thinking that it would increase drydown rate much better.
