One suggestion (which I offer as a general matter and not specifically to RP): At least in some jurisdictions, boards can delegate many of their powers and duties to committees of the board that can include some non-board members. (The board members should be a majority of the committee.) So if you have a board candidate who is really strong in one area—say, they have tons of experience conducting performance evaluation of senior staff—but isn’t the best choice overall, you may be able to ask them to serve on a board committee that handles the thing they excel at.
