If you decide to leave the liner in place, and then sometime in the future you absolutely must be remove, you can always get it out with an easyout. The liner may need to be drilled out a bit for the easyout to fit, and of course the liner will have to be replaced.
Heating the liner will make it expand, thus making it even tighter. Better to heat the barrel steel adjacent to the liner - that will enlarge the female hole. But I haven't had much luck using this approach with other stuck threads.
