Gute:

Bad idea trying to train tank and Bradley crewmen to rotate between ABCTs and IBCTs. Tasks are too differnent between an M1/M2 and a armored HMMWV.

IMHO, 2X2 Infantry Bn also not a good idea, not enough infantry.

Regarding RC cadre units for CS and CSS. A hat trick. When you need these units, you need them and don't want to wait while they get filled and trained up.

With another 100K of personnel cuts possible out of the Army, we have only seen the tip of this iceberg.
