Ahaha, don't get your hopes up, friend. The possibility of an adequate, degoogled Android with picky requirements as GOS on good, ultramobile hardware (matte DCI-P3 IPS, 3.5 mm audio, USB-C 3.2 or better, dedicated, ideally quick-access mSD card slot, IP68 rating, good cameras, EMR pen compatibility, changeable battery, non-plastic case) is virtually nil. That would essentially be a modern hybrid between a Samsung XCover Pro 6 and one of the older Samsung Note phones, e. g. the Note 9. Days long gone... :(
