I was talking about the parameter under [keystone_authtoken] 
([keystone_authtoken]/region_name) and not the new one under [keystone] 
([keystone]/region_name). It seems that we were talking about different 
parameters though so this explains that.

I will attempt this next week. Will update if I run into any issues. Also, from 
experience, most Openstack services seem to pick a random endpoint when 
region_name isn’t specified in a multi-region cloud. I’ve seen that several 
times ever since I've built and started maintaining this infrastructure.
