Sorry, didn't see it before.  
So I had it wrong when testing and used a regular `object` type rather than `nested`.  
I do think there's currently no way to use `nested` field types with runtime field.  
Based on this answer it seems that deprecated scripted field can provide some help manually accessing the `nested` structure via `_source`, but that will have some performance impact: [ElasticSearch aggregate on a scripted nested field - #2 by doogyatnesta](https://discuss.elastic.co/t/elasticsearch-aggregate-on-a-scripted-nested-field/298841/2)
