My only real issue is with the pickoff attempt limitations. For a runner to know that after 2 pickoff attempts, another one is very unlikely, is unfair. I know it says they can attempt it and if successful the out is recorded. However, if it is unsuccessful, they get the next base. Is limiting the number of curveballs a pitcher can throw during an at bat or the number of foul tips allowed for a single AB next?
The time part I am okay with. Stop the micromanaging from the dugout. Stop the incessant glove adjusting. Get up there and get the pitch thrown.
Bigger bases are fine.
I am also okay with eliminating the shift. Teams will probably make the infield dirt go further into the outfield. I am okay with 2 on each side of second base. I am not okay that they have to have "cleats in dirt" part. If the second baseman wants to get in the grass, that should be fine. So I don't think there is a defined dimension of the infield dirt, so expect that to expand.
