It would be an administrative nightmare. Every time your Hub IP changes, you'll have to go into each spoke and change it. Do-able but not advisable.

If you could get the isp to map your routers mac to an ip, you could get the same address every time via dhcp.

How about running something at the hub that registers with dyndns (www.dyndns.org) and use the dyndns registered name instead of the ip address in the spoke routers. I haven't tried it myself but it's worth investigating. The spokes are going to need some way of finding the hub.
