Don't overlook the simplicity and compatibility across different memory cards by using a ProDOS RAMDisk.  There are ways to organize your files on such a disk to get reasonable performance.  Perhaps not as fast as native access, but acceptable for many uses (think swap disk).  In any rate, it might be easier to mock up different scenarios using file access calls before committing to a final native design.
