Is it possible to project nodes/relationships to in-memory graph in batches?


I'm trying to reduce a multigraph to a single graph in order to run a community detection algorithm on it. See my discussion here for more context. I solved the crashing/out of memory issues by using apoc.periodic.iterate to create the reduced relationships in batches. However, I don't want these new relationships to be written to the database; I want them to be projected to an in-memory graph to be used for label propagation. My question is: is it possible to project nodes & relationships in batches using apoc.periodic.iterate? I've been playing around trying to use apoc.periodic.iterate within a cypher projection query, something like:

CALL gds.graph.create.cypher(
'MATCH (n:WebContent {networkId: 0}) RETURN id(n) as id',
'CALL apoc.periodic.iterate("MATCH (n1:WebContent {networkId: 0}) RETURN n1", 
"MATCH (n1)-[:Includes|Has_signature]->(m)<-[:Includes|Has_signature]-(n2) 
 WHERE id(n1) < id(n2) WITH n1, n2, count(m) AS weight 
 CREATE (n1)-[r:LINKED_TO]->(n2) SET r.weight=weight", 
 {batchSize:1000}) YIELD batches, total, errorMessages 
RETURN id(n1) AS source, id(n2) AS target, r.weight AS weight')

but no success yet (I'm not sure it's actually possible to access n1, n2, and r from the batches like I'm trying to do here). Just trying to get a sense of if what I'm trying to do is even possible at all... perhaps apoc.periodic.iterate is not the answer, but another method is?
