Will this in any way structurally compromise the bike frame, or create any other problems?

I'll echo what Rob_E says. I'd add is that you'll probably need longer rack stays. You may also have a problem with the angle on the rack stays on larger frames. This isn't that much of a problem for flat stays but round ones might be difficult to mount since they mount under the rack.

For small bikes...like 12" frames...using a seatpost clamp mount might result in shorter stays. This bike for example, would probably work better with a clamp mount
