It's not on the priority list.
Nearly all of the spell lists in there can be found in one of Rolemaster Companion I (currently available), Essence Companion (currently available), and the various RMSS/RMFRP Spell Laws (which are on the priority list).
It is also in essentially an incomplete state (lacks a proper front and back cover, etc) so it would not be just a rebranding exercise.
Best wishes,
