A few observations to make here:
Cabbages
I don't think the cabbage route is feasible given the monocoque design of the carbody. It's a stressed body, like an eggshell. Imagine trying to put a tiny rollup door on an eggshell...
Fleet size
I would assume that since there are almost 200 P's in the fleet and about 140 SC44's on order (state and corridor both), there's going to be 70-ish of the best P42's kept around for perhaps five years until the next order.
Maintenance Base
In the past, older fleets are usually consolidated at one or two maintenance bases where spares can be concentrated. Recall the last F40's ran the north end of the NEC, and the last of the Pooches ran Sunset and Autotrain. This might be hard to do considering the new SC44 is slated for corridor service out of most major hubs, including LA, Chicago, and Seattle, while New York has little use for straight diesels. I guess you could base them out of DC for use on all the LD's that change power there - Silvers, Crescent, Cardinal, Auto Train, etc... I don't believe Virginia bought any SC44's anyway. I know a new shop was built in Seattle for the SC44 so trains hubbing out of there will have the SC44 for power at some point.
As a side note, it's amazing how quiet they are! Last week I spent a bit of time on the Wolverine, which requires boarding on the south side of Chicago Union Station. The station is essentially one giant concrete tomb. It's filled with noise even mid-day when a few idling Metra locomotives lay up. While walking out of the north concourse stairways, the outbound Hiawatha passed me almost silently, and outbounds have to accelerate off the blocks and uphill. It was almost like a straight electric.
