I don't remember one but I don't read every thread either.
Seems like the end product would basically be the same as using an ultralight tube made for that size. The butyl would be the same thickness once inflated using a regular .9mm 20/25c tube vs a .7 28/32c tube. Just wanted to check to see if anybody has done something like this. Running two different sized tires now and don't really want to carry two different sized spare tubes with me.
