Currently, Special:Logs/delete will say, e.g.:
16:55, 2 October 2016 Foo (talk | contribs | block) deleted page Project:Sandbox (content was: "Bar") (view/restore)
16:55, 2 October 2016 Foo (talk | contribs | block) restored page Project:Sandbox (4 revisions restored)
There should be an "(affected revisions)" link, e.g.:
16:55, 2 October 2016 Foo (talk | contribs | block) deleted page Project:Sandbox (content was: "Bar") (affected revisions) (view/restore)
16:55, 2 October 2016 Foo (talk | contribs | block) restored page Project:Sandbox (4 revisions restored) (affected revisions)
This link would take you to a Special:AffectedRevisions special page that lists the revisions affected by that log event, whether they're in the archive or revision table. You could then select all the revisions and move them en masse to a page title of your choice.
