AZ was the first that I remember to roll the field in and out for sun and water, and to protect it from other events in the venue. They blew it this time with the grass not being mature enough (not rooted well enough), and having too much paint in some areas.The concept that Las Vegas stadium uses has a great possibility for what you're after in consistency. A surface that can be rolled out as a whole or in sections can be maintained/replaced and grown. There are always problems with any turf but it would be much easier to adjust a section in a tray than large portions of a field. In the long term the costs would be much less and injury risks dealt with immediately rather than at a season's end. It works well with the multi-use emphasis of most new stadiums as well.
Surprisingly the NFL hasn't publicly suggested they are planning to require something like this. The NFLPA should partner very hard for it as well.
