One course of action would be to send a message to
silverbooks@themayflowersociety.com and ask how to submit a documented correction to a Silver Book, if that is the source of the error.
It certainly is not "near impossible to get them to change their minds." Revisions to the Silver Books are constantly being published. They are frequently seen as articles in Mayflower Descendant, because it is the scholarly journal of Mayflower research. Volumes sometimes have gone into new printings with an addendum, giving corrections that have not yet been incorporated into the body of the work. Some of the older volumes are in their third edition, each new edition incorporating revisions to the previous edition.
That said, it is easier to get a Silver Book revision reviewed and incorporated if one is an already published Mayflower scholar. Which volume are you concerned with? I may be able to offer additional suggestions, depending upon the person currently in charge of that volume.
Another possibility would be to allow me to review your work, as I have the ear of HG Paul Bumpus. We have been corresponding by email for nearly a decade. We have recently been corresponding on an entirely different subject, but I daresay that if I find your argument compelling (and I would be willing to help you try to make it most compelling) it might be easier to have me recommend to Paul that he should examine and consider your correction.
