I agree, but I think that original case is OOP, and is the reason for a number of old motors being retired.
Shipping it as a SU version would still be hazmat. Unless they made it a loadable SU, and shipped the propellant as 2 grains. (The LMS motors don't seem to fly off the shelves, so making this into one is very unlikely.) That would also make costs higher.
Maybe there's a chance; if the NEW G8 and G12 have strong sales, then maybe they bring out a new G25 variant. (IF it would work as just a propellant and minor nozzle change on that even better. ) As LPR flyers best way to get options is to use the new ones they did come out with.
Just my 2 cents.
