The Old Big East conference extended from New England to Florida to Wisconsin, with a mix of football and non-football schools.

I know it didn't end well, but it was a pretty good 30-year run, with the conference routinely landing 8-10 bids in the NCAA tournament and automatic BCS bowl access.

The NEW WCC would extend from California to the Northwest to Texas, with a similar mix of football and non-football schools:

BYU = Notre Dame
Gonzaga = Georgetown
St. Mary's = Villanova
Pepperdine = Providence
USF = St. John's
USD = Seton Hall
Santa Clara and Portland = Marquette
LMU = DePaul

Pacific [kicked out]

SDSU = Syracuse
UNLV = UConn
New Mexico = Pitt
Air Force = Boston College
Colorado St. = ?
Boise St. = Miami
Wyoming = WVU
Houston = Virginia Tech
SMU = Rutgers
Navy = Temple (football only)

18 schools for Olympic sports.
10 football schools, divided into two 5-school divisions for the CCG, with only 7 conference games. (3xP5 OOC requirement)
Navy is a football only member (like Temple).

Football divisions:

WEST: Boise St., SDSU, UNLV, Colorado St., Wyoming
EAST: Navy, Houston, SMU, Air Force, New Mexico

BYU = independent football affiliate. Schedules 3-4 regular season games v. WCC opponents and eligible for all WCC bowl games, as long as within 1 loss of next available WCC team.

7-game conference schedule, with 4 intra-divisional games and 3 cross-divisional games.

WCC (including independent BYU) signs bowl deals with the the following: Fiesta (NY6 v. PAC/B12), Holiday (v. B1G/PAC), Las Vegas (v. PAC), Military (v. ACC/B1G), Armed Forces(v. B12/CUSA), Hawaii (v. MWC/CUSA), and Miami Beach (v. AAC).

Olympic sports schedule:

I believe the OLD Big East played everyone in the conference at least once, with a couple of opponents twice. That could work for the New WCC, or you could divide into scheduling divisions (with travel pairs next to each other):

NORTH: BYU, Boise St., Gonzaga, Portland, UNLV, SDSU
SOUTH: St. Mary's, USF, LMU, Pepperdine, USD, Santa Clara
EAST: Houston, SMU, Air Force, CSU, New Mexico, Wyoming

10-4-4 schedule (or 10-5-5, if you go to 20 games).

EDIT: This is essentially a merger of the original 8 WCC schools and the original 8 MWC schools, minus Utah, plus Boise St., Houston, SMU, and Navy - to beef up the football.
