Bad Things would happen, but I only have one router and since it's a NAT box
it isn't very likely to end up in a routing loop anyway.

What I wanted to do was be able to send my traceroutes to websites that
don't function properly, but since my NAT box is headless and I'd like to
avoid the hassle of SSH-ing to it, I do these traceroutes from one of my
internal machines. If I don't manually remove my NAT box from the list, the
braindead webmaster will allways blame my NAT box (which naturally is
innocent;)). But I suppose you do not want this to be possible. That is
understandable, but still BSD has a very clean implementation of
transrouting and I see no reason not to let Linux do this.
