I would suggest it be a custodian for Sheldon's red star, not an adopt-a-member or just a current non-red-star member. I think it should reside in the Bicycle Mechanics forum where Sheldon was most active and made, overall, the most significant contribution to cycling.
And I would suggest for consideration members such as Retro Grouch (who also freeranges over to Classic), Hillrider and several others who, in my humblest of all opinions, make excellent contributions in the spirit of Sheldon Brown.
