Mark, As Joe mentioned it certainly is possible and feasible to run the 4 devices in parallel (2 ios + 2 nx-os) but just because you can do things doesn't mean you should. With that said, I was just make the effort to try to minimize how long you have things running in such a format. With this topology in place it does make you be a little more 'disciplined' in your activity from a layer3 perspective, such as requiring 4 peers with your upstream routers or mpls routers, in addition any route-maps or prefix lists would need to remain accurate across them all. Also if you're running vPC's on the 7k side of things that has the potentially to throw a minor wrench into the STP aspect of things.
In the past when migrating from 65xx over to 7k's at datacenters, I have thought about doing the same but typically just pull the band-aid off and switch the layer3 functions off the 65xx's into the 7k and turn the 65xx into pure layer2 switches with a "default-gateway" statement and a vlan interface for management ability. Another option is to do what you're saying but at the end of the change shutdown the 65xx SVI's to only keep the 7k SVI's up. With priority/preempting you could bring the 7k's into the HSRP mix and then during that same change work the 65xx's out... The above are just "thoughts and suggestions" nothing more, as every environment is different.
