Alumni Football Game

Homecoming is a pretty big event at UM. My sorority AGD has always had a close relationship with DU (and LXA) on campus. The relationship was renewed last year when DU came back on campus and this coming fall they will be living in their old house (HUGE) which is across the street from ours.
I know how much our alumnae love their alumni(?), and was thinking maybe we could have a DU/AGD football game annually when its Homecoming.

1) Does anyone think this would be a fun thing for alumni to particpate in??? (We could play with the collegiates too of course)
2) Would it make an even better charity event? Its on one of the main roads to the stadium and I am aure ppl would stop and watch. Kind of like SAE's Mud Bowl.

Suggestions??? Thanx!
