I'd have to question the viability of a Physics major with just one full time
faculty member. When my kids were looking for colleges we considered some
schools with only one or two faculty in majors they were considering and
decided against them. There are always exceptions, but I figure the faculty
member needs people to talk to and that students need exposure to greater
diversity at the undergraduate level. Perhaps your logic is to build your
program so you can hire more faculty so you do have folks to talk to.
Otherwise it makes more sense to me for you to concentrate on a two year
program, with students transfering to a larger program for their Jr and Sr
years.
