This status will be offered in the future as well, you just need 600 nights. So assuming you're going to keep up a health travel pattern for the next 3 or 4 years then just book as you usually do as make Lifetime Platinum with the Marriott combined program.
Even if you had a few years of slow travel, you still have the 10 years of platinum, so once you hit 600 nights, you'll be good to go.
Seems crazy to do a 56 night mattress run.
