No - no pressure concerns as long as it doesn't leak. If you can find a piece of copper tubing to make a sleeve over the existing tube, that should work.... cut out the bellows and solder the sleeve over the remaining ends. It should be fine as long as the stay braces are securely bolted to the upper plenum for support and vibration damping.
