This could potentially be dangerous as it is causing the burner to heat up hotter then it should be. Tha is the reason the wind screen has holes in it. So I would use it with caution.

Here's something to consider...

wood burning stove/alcohol stove stand (click on the Penny Wood Backpacking Stove link)

...should work great as a stand for your Trangia mod (or any other small alcohol burner) and give you the option of burning sticks, pine cones and such as fuel if available and need dictates. At 3oz, it seems like a great addition for little loss of space and weight gain in a BoB.
