Sounds really awesome! Even now MAAS has 90% of the problems with deploying clusters solved anyways: discovery and power control (if you have power control you have metrics and hardware reading for later monitoring during production, etc etc)
A bit more of work and would make such a great platform for HPC. Any who, will leave the juju list to do what it does best, thanks for listening.
