Scott, having a strong interest in hockey and hockey history as well as in baseball and baseball history, we followed with considerable interest
a similar "revisionist Hall of Fame" project conducted some years ago by the SIHR (hockey's version of SABR).
Nominations for "virtual enshrinement" were presented by only members of a select committee, who then debated and voted on the nominees.
The process, which may give you some ideas on how to organize a Net54-selected Baseball HOF, is detailed here:

The major question for a Net54 HOF project is raised by the size of Net54 membership and the widely varying level of participation
by Net54 members. Is everyone to be allowed to nominate and vote? Or will that activity be restricted to a certain smaller committee,
or to members with a minimum number of posts, or... ?
If nomination/debate/voting is to be limited to only a committee or to otherwise qualifying members, then any agreed-upon percentage
of "yea" votes between 51% and unanimity should enshrine a nominee.
If nomination/debate/voting is to be open to all members, then you'd probably want to go with a minimum raw total number of "yea" votes.
Just some early thoughts...
