Why return nodes/relationships if you only want a single property:
g.v(1).out.in.myProperty

I don't know enough about the REST API and Gremlin, but have you tried:
m = [:]
g.v(1).my.groupCount(m).based.traversal >> -1
m
where you need the 'm' at the end to return the map.
Or are you saying that m can't be converted correctly to something Neo4j
managed extensions can understand and JSONify for you?
See ya,
Marko.
