It is a bold, unconventional move, no argument there.
If BC can get their fans to buy-up tickets (admittedly, I am not sure how many tickets will be available for BC on the first- or second-hand markets) and show up, and then win the game on the field, I'd say BC comes out smelling like a rose... and Notre Dame looks ridiculously foolish and arrogant for arranging this. (And then to think Notre Dame will be coming to Chestnut Hill soon after for a BC home game? Have cake and eat it, too.)
If I can have a "road game" with zero travel expense for program (and local fans), zero inconvenience for the so-called student-athletes, much easier geographic access for fans to a "road game" (though admittedly ticket access could prove difficult) while still retaining a full allotment of home games (including a subsequent visit by ND), it looks like a great business deal for BC.
If ND fans dominate the stands and dominate the play on the field -- as they MUST feel they will, to schedule something like this -- then BC is totally embarrassed and likely never does it again. Lesson learned, prepare for ND's subsequent trip to Chestnut Hill.
I personally thought it was lame of Florida State to move their 1994 game with ND (a Seminole home game) to Orlando. Yes, Orlando draws well for the Seminoles, but Orlando also opens things up a lot more for ND fans -- hence why ND eagerly agreed to it. I would have thought a true FSU home game versus ND would have been epic for Seminole fans -- with a dearth of ND fans -- but FSU indeed moved their own home game for Notre Dame. (FSU has subsequently moved Seminole home games versus Duke, Wake Forest, Colorado, and Alabama to Orlando or Jacksonville)
