Thinking out loud-vCenter server on Hyper-V

Today i was thinking about a scenario, where i was thinking to put vSphere infra components (Like vCenter server, syslog, AD, DNS, DHCP etc.)above Hyper-V Cluster.

i know what you're thinking, what absurd thing i'm talking about, what is the need of separate management cluster, Hyper-V is not mature enough to host vSphere Management infra., VMWare and Hyper-V don't go Hand-in-Hand etc. and i accept that, because before conceiving this concept i had same thoughts but later i cross questioned myself i.e. what is pros/cons about this design and how this is going to help the customers. So, i'm sharing the pros/cons about this design with you, if you any comments whether good or bad, i'm all ears.

Pros or advantages:-
1)Dual Hypervisor strategy with a twist.
2)Most of the vSphere infra components require windows OS (yeah,i know about VCSA).
3)Utilize "Virtualization-Safe" feature introduced in win2012 (VM-GenerationID, avail. with Hyper-V v3), make SSO robust.
4)License cost reduced (at least for management cluster and OS license).
5)Utilize existing hardware and windows OS license.
6)vCenter server supported on virtual platform (kb10087), nothing mentioned about Hyper-V

Cons or disadvantages:-
1)Requires multi-talented engineers to manage.
2)Support-issues from both vendors (support engineer love this sport, Volley-ball).
3)Some Third-party software issues (i don't know which, but included it).
4)Hard to convince CIO/CTO's (biggest threat to such designs)

If you have something in your mind about the above conceptual design, please share your thoughts.

thanks
