Unfortunately I don't believe it is possible to get your hands on the blueprints or even edit a rod shop, unless you built one yourself.
however if you're an admin on a server or playing singleplayer you can move rod shops by using the admin commands;
(export_sector) - Exports the whole sector. Be sure to use /force_save before [X(Integer), Y(Integer), Z(Integer), name(String)]
/export_sector
2 3 4 mySavedSector
^^^
(Put you own coordinates in place of these ones).
and
(import sector) - Imports the sector you saved.
/import_sector
5 9 0 mySavedSector
^^^
(Put you own coordinates in place of these ones).
Hope this helps
