If you're good with soldering you can change it, otherwise it is a lot of work to do for a common board that is available in other switch types. If you are going to go to the effort, might as well go the extra mile and sticker and lube the transplant switches too before resolder.
If I were you I might try trading first, though it might be difficult, or otherwise just sell it at a slight loss and get a different board with browns.
