Problem is it just doesn't work like that anymore. The baseline art required for a 22 page book is substantively different than it was 40 yrs ago, but the deadline is the same, and the pay hasn't risen appreciably (from what I hear) since the late 90s. Large scale plotting for the big companies like Marvel is generally worked out at their writer's retreats and is absolutely done months and months in advance. Individual issues just take a long time to finish with art chores, edits, and rewrites.
To even approach it you'd need 4 artists a year on any given title, and the thing nobody can account for is if one of those stories in the year is a flashback set during WWI and the landing at Normandy, it won't matter how shit-hot the artist is, they simply cannot get a page of that done as fast as the next story down the line that's set in a desert or in space (or any other place where the background and number of characters is lower intensity).
Generally I think it should've been leaning into graphic novels without strict deadlines for a while now for a lot of reasons.
