Pros of a CMP format with 8 60-team divisions instead of 4 85-team divisions:

More teams get to go to CMP
Twice as many teams get to compete in Eliminations at CMP.
Everyone gets to play more qualification matches, which means the elimination alliances *should* be better quality, due to a more accurate ranking.
Full elimination bracket on Einstein

Cons:

(For reference, an NFL field is 360x160, or 57,600 sqft)

Need 13 fields. (Based on Week 3 this year, 14 Logomotion fields exist, possibly 15, since I understand FIRST HQ keeps a spare field in a truck ready to go at all times through competition season.)
Need space for ~13 fields: 8 divisional fields, Einstein, plus 4 practice fields. (50x80' footprint each, 4000sq ft * 13 = 52,000sqft.)
Need space for ~500 teams (10x10 pits, 50,000sqft)
Need seating for ~500 teams worth of people (500 x 20 = 10,000. 10,000 people on 24" centers = 240,000" of linear space, or 20,000 ft of grandstand rows which are usually 2.5' deep, so 50,000sqft of grandstands)

Thats 152,000 sqft, before you even account for aisleways, and all the sponsor booths, and FTC/(J)FLL/Collegiate stuff.

8 divisional fields, plus a 9th field (einstein), plus a 10th field sized footprint (FTC) = 40,000 sq ft. it CAN be fit onto a NFL field, especially when you consider the floor of an NFL stadium extends past the edges of the football field. (This is why i also don't understand the need to move 2 fields into the pits this year. Dome floor has TONS of space)

The 10 footprints could be stacked 4 end to end, on each side, with 1 between the sides on each end. would result in a 320x180 total footprint.
