Yes it is possible here. Here is a sample configuration that I have
running on a pair of Cat6509 with Sup2 MSFC2:
Switch One
--------------------------------------
interface Vlan340
ip address 10.120.4.3 255.255.255.0
no ip redirects
standby 34 priority 99 preempt
standby 34 ip 10.120.4.1
interface Vlan350
ip address 10.120.5.2 255.255.255.0
no ip redirects
standby 35 preempt
standby 35 ip 10.120.5.1
Switch Two
--------------------------------------
interface Vlan340
ip address 10.120.4.2 255.255.255.0
no ip redirects
standby 34 preempt
standby 34 ip 10.120.4.1
interface Vlan350
ip address 10.120.5.3 255.255.255.0
no ip redirects
standby 35 priority 99 preempt
standby 35 ip 10.120.5.1
For layer two configuration, I have the gigabit ports on the sup
connected as ISL trunks with backbone fast. Servers are dual niced into
each chassis.

This is possible with 2 sups in the same chassis, however, if you have
two separate chassis with their own Sups, then I don't think it's
possible to have one act as a "mirror" for the other. You could
configure the RSMs (MSFC's, whatever) with HSRP, but that wouldn't do
what you said you wanted. Even with HSRP, the "other" interfaces on each
RSM would need to be configured with their own IPs, etc, thus not
satisfying your requirement to have "a second switch with a copy of the
primary's configuration". Unless you have the end devices connected to
both switches, your screwed anyway if a sup dies (unless you have a
redundant sup installed in which case you're not utilizing the "other"
switch).
I do not believe that what you're looking for is possible with to
completely separate switches like that.....
