They will go to field turf 10 times over before the even consider that solution.
As someone already pointed out, players want to play on grass, and how "bad" the field looks to us makes no difference. Heard ND Kalu on the radio earlier in the week discussing this, and he said he had no problem with the Texans field when he played here. He said it was a little harder than other natural grass fields, but much better than any artificial turf he played on.
Open air stadium are constructed to allow full sun to the grass and extensive as-needed watering. Grass on pallets to begin with are more difficult to care for. Not moving the pallets out for periods of time can have a negative effect on the grass. Moving the pallets too often can have a traumatic effect. Watering techniques and needs inside and outside the stadium differ and their effects on the grass can be significant. Once the grass is damaged, return to "health" within a pallet is a much more difficult and lengthy process than if part of the natural ground. All of this, along with not replacing the pallets as needed, has very damaging effects on the root systems, resulting in cleats throwing clumps creating holes and divots throughout the field. I spoke to one of the grounds keepers involved in the care of this system near the beginning of the stadium's existence who mentioned a significant concern of these clumps coming up right at the seams of the pallets creating significant hazard spots where pseudo separations would easily catch a player's cleats.
