If you remove the control arms it's probably not too difficult to fabricate a little press to get the bushings in and out. I'm pretty darn sure the bushings won't just slide out though and will require some convincing and swearing. I think when the control arm bushings wear out it's a good time to do the M3 arms. If you're paying a shop to do the work, I'd say the M3 arm swap would be pretty close in price than just swapping bushings.
