Would this be possible? (D850) topic

Would any of you guys be able to pull out the stock kernel and the Lollipop baseband from the latest (Lollipop) update dor D850? I will be experimenting with other carrier roms, but I need those two key components to make this work. If you would direct me to where I could be find them, I'd be foreverr in your debt. Thanks.
