VPC on Nexus 2Ks

So my setup is a VPC with 5Ks and with each 2K with uplinks to only one 5K.  Is it possible for servers to port-channel to both 2Ks for a VPC?  Or is that only possible if the 2Ks have a VPC back to the 5Ks?

I think that would work.

I think that would work. depending on the fex type.

From NX-OS 4.2(1)N1(1), it is posible to connect a server with vpc to two fexes that  are single attached.

From NX-OS 5.1(3)N1(1), it is posible to connect a server with vpc to two fexes that are dual attached with vpc, this is called enhanced vpc.

see this for example

That would work only if each 2k was connected to both 5ks (VPC).
