I dont know that conversion is an issue, at least not for the use of Calibre. If the schools choose readers that can read various formats and then make sure that texts that they purchase are in one of those formats then all is well.
The problem would be if the schools begin making text book purchases based on whether or not they can be read in their reader and not based on the merits of the book itself.
