Let's assume the 6+6 format, or a straight 12 format, with December first round games and New Year's Day quarterfinals. (One QF on either Jan 2 or Dec 31). 2 Semifinals in January and then a National Championship game. And at least 7 days between rounds--nobody should be playing a playoff game on 6 days rest.
CFP honcho Bill Hancock has said that the NCG is on a Monday because fans have to travel, and a Monday is at least weekend-adjacent.
The NFL season will now run 18 weeks, with 2 Saturday games on Week 18, and 6 playoff games on Wild Card Weekend--2 on Saturday, 3 on Sunday, 1 on Monday.
So Saturday is out, Sunday was never an option. And now at least one Monday is now spoken for.
That leaves Friday, and since there are only so many hours in prime time, a game on Thursday.
So something like
First Round:
2nd/3rd Saturday in December. 2 games on campus
3rd/4th Saturday in December. 2 games on campus
EDIT: I forgot that the NFL now plays a Saturday night game in Week 15, kicked off at 8:20 last year. So at least one of these games kicks off at noon or so.
Quarterfinals
New Years Day (or Jan 2). 12:30 QF bowl, 5:00 QF Rose Bowl, 8:30 QF Bowl.
New YEars Eve: QF Bowl (If Jan 1 is a Sunday, 4th QF is probably on Tues Jan 3)
Semifinals
SEcond Thursday in January (Jan 8-14)
Friday, Day after Second Thurdsay (Jan 9-15)
National Championship Game
Friday, 8 days after Second Thursday in January. (Jan 16-22)
Or Monday, 11 days after second Thursday in January. (Jan 19-25). Edit.
Comments? Did I miss something important?
I'm assuming the Rose Bowl gets a permanent QF slot, and lets the other 5 NY6 bowls rotate the 3 QF's and 2 semis, and the semifinal bowls don't play a New Years' Day/Eve/Week game.
EDIT: Here it is in more calendar-ish form.
