What diameter post do you need? The reason why I ask is that my Swift came with a steel post that is 530mm long 28.6 mm outside diameter and 25.4 mm inside. Since the Thudbuster comes in a 25.4 size I could get one and insert it into a steel tube like the post that I have, and I would have a thudbuster shock post setup for my swift. There would be a small penalty on weight. If your post diameter is large enough that you could get a tube with a 25.4 ID and an OD to match what you need for your seat post you can make your own.
