Yes, it is possible. But in some cases it is not so easy. I don't want to maintain several proxies for simple tasks. And we loose pool of open connections functionality for example. I think that to implement simple access&deny filtering not so tricky.
I don't know what OS you're running on, but a simple solution for Linux users would be "iptables", for example denying locally generated connections from the source port and IP on the local machine on the 'OUTPUT/mangle'. Other OS/firewall combinations will vary, of course.
