Bus transfers

I have a campus project with public bus service on all sides and one through the middle. A person can walk to three bus stops serving 2 public bus lines and the campus shuttle within 1/4 mile. What I'm looking for is research on whether I could also count a 4th bus stop that serves a 3rd public bus line. This stop is .27 miles from the building, but could be accessed by getting on one of the public buses at a closer stop, riding 2 blocks on campus, and then change to a public bus on the 3rd line. The rest of the "shutle" variables seem to be met, less than 2 miles, ride of 5 - 10 minutes, available to everyone, etc. I know that bus transfers to other bus lines at hubs are not allowed, but does anyone have experience with or an opinion of an on-campus transfer like this?
