Stop.  You're the one who wants one router (probably an original default
route for your hosts) to tell other connected routers about new subnets on
an existing segment.  If you already have one router on the subnet and
you're adding a second router, what do you care about static defaults?  

You're almost asking a dynamic routing protocol to insert a magical HSRP
configuration into any adjacent routers.  Wake up and stop dreaming.
Besides the fact that you're asking a layer 3 protocol to handle your
layer 2 and layer 1 issues, you're asking a layer 3 protocol to do magic
reconfiguration.  Dangerous stuff, as soon as someone on that network
finds out what sort of havoc they can create.
