You would need another spare interface on the "A" and B" router and then create the subnet on each along with the hsrp config like you have for the other subnet . The only other way is if the L2 switch is a managable switch like a say a 2960,3560 then you could take the existing setup and create trunks between your existing routers and the layer 2 switch which would carry both subnets and then plug the 6500 into the existing L2 switch in which you have created vlan 100 and carried that across the trunks. This scenario still leaves you with a single point of failure though at the L2 switch. The way you have it on your diagram is a single link and there isnt a way to do it that I know with the way you have it on the drawing.
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
