From the specs of the xl, it runs at the same speed as the non-xl, so I wouldn't expect it to reduce the CPU, but with the additional resources on the xl for dealing with many routes, not 100% sure it wouldn't help.
I also wonder whether different line cards would make any difference, such as the SIP series using Ethernet ports. It might depend on what is causing high CPU and what the line card's local processor supports. Again, not 100% sure, but ordinary DFCs might only handle DCEF where some of the SIP cards might be able to off-load more. (I know some of them support QoS features otherwise unavailable.)
Lastly, also not 100% sure the group BGP peering reduction only would be against "BGP router". From Cisco's document I referenced in my prior post, "Based on the number of peer group members, the number of prefixes in the table, and the number of prefixes advertised, this can significantly reduce the load." Since this is just a configuration change, if this feature is supported on the RSP, something you could try before swapping supervisor or line cards.
Again, not 100% sure, but I recall reading some PBR statements have a higher impact than others, perhaps your policy had statements that caused some form of process switching. If you haven't already, and if supported, you might also try policy cache and/or flow cache on your interfaces.
