Yes not close enough for me
Now your crank is under balanced which is not a good thing over balance that much would be fine 31 GRAMS under balanced is a lot!!!!!!!!!

Which weighs more 25 lbs of wet sand or 25 lbs of dry sand.
They weight the same,
Your new pistons don't.
I would most definately get the rotator balanced.
