As far as I understand the proposal, the goal is not to solve all AMS problems, but rather to lay the foundation for doing these kinds of optimizations and deal with a few assorted ones (most likely auto-mod will be a candidate). Thus, I think Erik's proposal sounds feasible, although I'd expect some of the allocations/priorities in the schedule to change during the project. But that's not something unusual to happen.
