It seems to me with population declines and growing cultural hostility it makes sense to try and work outside or alongside the system, avoid code requirements, limit overhead, share resources, and generally move away from the large brick and mortar idea of "school" that has become the norm in American society. Many congregations have underutilized facilities. Viewing such buildings as blessings with great potential rather than as burdens to bear might offer new perspectives on what is possible. Such buildings serving as a hub for a homeschool co-op or one room school house for several families or congregations makes great sense, especially for establishing new schools.

I've often thought if you could combine the Classical Conversations model of campuses with tutors and the Teach for America model of recruiting and training young adults for two year service periods it would be possible to staff dozens of such 'non-traditional' schools in existing, and currently unused or outdated buildings owned by parishes, while also immersing both teachers and students in a classical Christian environment. Possibly throw in housing for your tutors in unused parsonages, and you could have a comprehensive and scalable model that could also be tailored to local conditions. Certainly a small group of creative and committed families can pool resources to provide an excellent, Christ-centered education for their children.
