I am going with Plan B, a Sierra Club Peakclimbers one-nighter backpack in the area you've been thinking. The negative 1 degrees Fahrenheit anticipated temperature at 12,000' for Friday in the Whites, together with the desire NOT to risk being snowed in in a rented SUV at the end of a long, largely unmmaintained at this time of year, dirt road, did me in.
I'll shoot/PM you details in case you are interested. There is still space available.
