I carried through with my proposition, and have played all my single-player SMAX games with these changes since. Ultimately I decided to not to tamper with the tech pre-requisites for MMI and Doctrine: Air Power, and boosted the strength of Plasma Shards up to 14.
Since then I've observed a far more balanced game, IMHO.
