I don't think this is such a good idea. I could reconfigure my system such that it's loop back interface was not in the 127.0.0.0/8 network and set a route to the 127.0.0.0/8 network to be via your IP on the LAN. Assuming that your system and my system were on the same LAN and subnet and we could ping each other I would be able to access your 127.0.0.1 address as your kernel would forward traffic to the loop back network in your system.
