Yes, you can heat them out with a heat gun - just have to really keep an eye, you can damage the carbon - boiling water also works for some but don't use an open flame (torch).
Or if you plan on re-fletching anyhow just strip the vanes, bare shaft shoot them (can do years of reading on bare shaft tuning) and then cut them down 1/4 or 1/2" at a time from the nock end until you like how they fly - refletch and shoot away.
