Yes it's would be very nice to hear about this kind of infrastructure using lxc/lxd 
I'm not yet ready to make this kind of testing, but if someone would like to work on this with me as a projet, I can provide the technical infrastructure and scripts . 
That would be nice to provide a good testing case and analyse to share to the community
