Man I’d love for that to catch on, mostly so it’s easier to learn. Kids get confused by the order all the time. It’s even shorter in some cases.
Also, the reverse order makes dictating phone numbers such a pain.
My kids grow up with multiple languages. I told my daughter early on not to bother with German numbers larger than 20, and to select a different language to do math in her head.
For a few years she was just saying larger German numbers like 9-2, or was writing them down, though now at 7 she seems to get better at converting them correctly.
