It would depend on the actual hardware components of both the 6500 and the 4500, and how they are configured and used. (NB: depending on actual hardware components, configuration and usage, a particular 4500 could be a "better" core switch than a particular 6500.)
Yes you could connect the 2 switches via a L2 trunk and run HSRP between the 2 switches. If one of the switches went down the HSRP active gateway would move to the other switch.
But and it is a big but, it really depends on what you are using your 6500 for. If you have for example a service module such as the FWSM then clearly the 4500 cannot act as a backup for this. And because the 6500 provides quite a bit more functionality than the 4500 without knowing exactly what you are using it for it is difficult to give a yes or no answer.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
