...even if the new school does not remain commercially viable, it may not be a risk per se, but rather one great year which may become a benchmark by which all other educational experiences are measured.
I agree with this sentiment. Our own experience is that changing schools can be a very good thing. However, it's important to identify whether the new school will be accredited and, if not, whether the students there would be considered homeschoolers. There might be some ramifications or paperwork, especially if the children rejoin the district later.
