This isn’t an easy undertaking and as @martin has said its “a moving target” and @splificator “where do you stop?” We are coming at this like cocktail people 
. Making sure the balance is perfect-- a base of historical recipe books, with a small dose of cultural literature, and a rinse of esoteric necessity.
At this point, for the sake of getting it done, I will bow out and leave this to the professionals-- there are plenty of them here much more learned on the subject than I. This task maybe shouldn’t be open to the public at all? I doubt the Vatican would open a public forum for the arduous task of whether or not to add or remove a book to/from the biblical canon of scripture. Like a patron sitting at the bar, I will stay out of the shaking and stirring.
In the same sentiment, I would almost instead be presented the canon of cocktails ala a cocktail list at a bar and choose whether or not I will personally be ordering from it or going off the menu. Maybe pick the best and brightest of this group to lock down what should be canon privately and then open it up to the public for amendments/adjustments through a voting system or a debate on one work at a time that should be added or removed thus creating the living list. I think this is where my suggestions would be better utilized and easier to promote/defend for ratification. Creating a system for amendments to the canon would be neat…no white smoke needed.
Either way, I have enjoyed rubbing digital elbows and I am excited to see where this goes. I’ll be over in what we’re drinking having a Martini 
.
