I'm not sure why you would want to do this? BGP can run (especially
IBGP) over many hops without any problems, but you still need to think
about the traffic that will flow across your network between BGP peers
and how that will be routed.
If you wish to form an overlay network with tunnels then you'll have to
ensure you next-hop processing is right I would think. However if you
wish to access the BGP destinations from outside of that overlay network
you'll need to use some some of default routing (or large scale
summarisation between the BGP and IGP domain).
