I just did a quick – very quick – check of the core requirements of both Canisius and St. Bonaventure.
Canisius requires two philosophy courses and two “religious studies” courses. Does not appear that any substitution is allowed for the religious studies courses, although one of these requirements does allow the student to choose which course to study. Students can choose to focus on non-Christian religions, including ancient Greek and Roman religions and religions in China. Zen and Meditation is also one option here.

Bonaventure seems a bit more vague but appears to require at least four courses where religion is a major focus: (CLAR 101, CLAR 206, CLAR 207, and CLAR 304).

You might want to ask people at these two schools how flexible they are about substitutions.
