Clustering doesn't do anything remotely of the sort.  It's purely 
management, and seems to be going away.

You'll want to setup a VLAN Trunk between the two stacks, however, I'm not 
sure how the L3 portion interacts there, but I *THINK* you could use HSRP 
or just intentionally assign the same IPs to routed interfaces on both 
sides, then let the L3 trunk carry the cross switch traffic.  I think.  Not 
really sure.

Whenever encountering something like this I've engineered around it by 
routing between the stacks rather than maintaining a single larger L2 
domain.
