You can create a script that uses Special:Export to export all articles in the deletion categories just before they are deleted.

Then import them into your "Deletionpedia".

Hi,
I am thinking about how to collect articles deleted based on the "not
notable" criteria,
is there any way we can extract them from the mysql binlogs? how are
these mirrors working? I would be interested in setting up a mirror of
deleted data, at least that which is not spam/vandalism based on tags.
