I saw this post on another forum: Modifying a Trangia for use with an Omnifuel. The individual made it work, but it took more doing than I would have expected. I've seen other posts elsewhere that made it sound easier, but the above post was detailed and had photos.

He did not need to remove the valve-at-the-burner control, but he did have to widen the opening in the lower windscreen. Widening the holes in the lower windscreen doesn't sound too bad. The part where he lowered the burner sounded more difficult.

I'm periodically researching this as I have time, hence the occasional odd post (such as this one). I'll post updates as I find out more.
