Hey Doug,

IIRC there wasn't a lot of support for MLT in cloud mode a few years 
ago, and there are certainly still a few open issues around cloud support:
https://issues.apache.org/jira/browse/SOLR-4414
https://issues.apache.org/jira/browse/SOLR-5480
Maybe there are some hints in the ticket comments about different ways 
to do what you want.

Cheers

Charlie
