I suppose it depends on the specifics of your routing and configuration, 
but my Asus RT-N12 router can handle this, in fact I believe this is a 
common feature with Tomato/DD-WRT/OpenWRT firmware as well. In my case, 
the router WAN port connects to the cable modem. The router gets the 
DHCP lease from the cable modem. Then I plug in whatever I want to the 
wired ports and can configure multiple wifi access points -- and they 
can be restricted to only the WAN or to also access the LAN side. 
Basically it is the implementation of your idea mentioned above.

I'm having trouble fathoming why you'd need a second internet connection.
