Ennhh - longer stuts for better engine clearance does not
require a 4-wheel bogey. Just - a longer strut.
The MAX10 was already planned to have a "shrink link" on the gear plus an extension lever - to give another 9"/24cm of strut length at rotation, while still fitting into the 7-8-9 wheel bay.
I notice Boeing just announced an expected write-down of $4.9 BILLION due to the MAX8 mess - that would have paid for a
lot of landing gear mods.
