XPS15 has 1080 to 4k display, up to 32GB RAM and is 17mm thin (in the base, the screen adds up a couple mm).
Battery is rated at 17 hours on the 1080, and this is a number that I've actually confirmed while working with a friend who owns one.
The 4k should get you to 10 without big problems.
Also, you do know that you are limited to 1200p scaling on the 15" MBP, don't you?
