impractical for an airplane
Depending on how much effort you're willing to put in, I would suggest switching material.
Use fiber reinforced plastic.
The process can be done at home, though you may need some practice. You can print the shape you want with a thicker wall thickness and then use that as a negative. You get the best results if you have a compressor and can use vaccum techniques to get the excess plastic out of the material. This will put you in the thickness space you want, and it will still work, and you don't have warping problems.
The klingon one is meh, because klingons don't cook their food.
But if I gatekeep that too hard we get less cool stuff, sooo... I'll allow it 🤣
