The BC Wanderers wandered for two seasons: 1986-87 and 1987-88. In 86-87 they played both 'home' games vs BU at the Garden, but in 87-88 they played their lone 'home game' vs BU at Matthew's. Here is where they played those seasons:
1986-87
10 Walter Brown (including 2 NCAA games)
4 Matthews (including exhibition vs Moscow-Spartak)
3 Bright
2 Garden (both vs BU)
1987-88
9 Walter Brown (including exhibition vs Team USA)
3 Matthews (including game vs BU)
3 Bright
2-year totals
19 Walter Brown
7 Matthew's
6 Bright
2 Garden
For NU the best option might be at a renovated Walter Brown (I find it highly unlikely NU can start work before WBA is renovated). BU might even be willing to have their women practice and play at Agganis while both NU teams practice and play at WBA, making scheduling much easier. A second option might be both men's teams using Agganis and both women's teams using WBA.
Using Conte is likely a non-starter, what with BC needing it for 4 teams already. Bright-Landry is the only other realist option. The TD Garden is a non-starter for practice, and probably too expensive for games, as well as having scheduling issues.
