Regarding noncanon Mirandas
, Memory Beta has a pretty comprehensive list that includes FASA and other such sources that once held "official" status - that is, they weren't produced without Paramount's permission and blessing and demand for a cut.
FASA didn't really create a list of ships for the TNG era, but the TOS movie era Mirandas
actually fall in the registry range you seek, being of the NCC-26XXX format. Also, here's a fan-compiled list to all FASA ships by class, including all they ever wrote about the Miranda
Beware of popup commercials, tho...
