We can extend your data model with a Vote node. Each Fact/Topic pair can have a shared Vote.
(t:Topic)-[:HAS_VOTE]->(v:Vote)<-[:HAS_VOTE]-(f:Fact)
(u:User)-[:VOTED...
If you're only looking at nodes and relationships with the structure of

you can try the following query
MATCH path=(u:User)->[:IS_MEMBER_OF]->(:Role)->[:HAS]->(ar:AccessRight)
WITH u, ar, collect(p...
I can answer your first question, with apoc.refactor.cloneSubgraph: apoc.refactor.cloneSubgraph - APOC Documentation
e.g.
MATCH (s) where s.version_id = 'version-1'
WITH collect (s) as nodes
call apoc.refactor.cloneSubgraph(nodes)
YIELD output as o

WHERE closing._text IS NOT NULL
AND specials._text IS NOT NULL
