You might get close by starting with the French carabinier helmet, cutting off the metal crest then re-attaching the caterpillar and trimming the 'tail' end to fit. You would have to smooth off the front part of the helmet and attach a small oval plate and chains - you can see them clearly in your photo of the Baden dragoon.
Assuming that the Baden helmets are the same as the Bavarians, just above the peak there is a horizontal metal band bearing the regimental name (I think, I can check my references later). You can see the band in your pic.
Well, here's my WIP. Not going to be putting any real sculptors out of business. Managed to move the caterpillar down. Couldn't get it more forward. Added chains, an oval plate, and a suspicious looking side plume. Only 9 more to go? ? ?
