offset grinding crank

Here is an odd idea that I think might work but I want your input incase I missed something.

What I have is a stone stock 74 - 360 short block that is in near perfect condition. This is a low compression motor with flat top pistons in it that are .080 below deck heigth. rather than buying new pistons and rebalancing the motor I thought about having the crank offset ground .080 to end up with a zero deck motor with high compression. To my figuring, since this is a Detroit balance motor and nothing is changing weight from the rods out. With the crank already balanced for these rods and pistons nothing changes there, with the .080 stroke change the same amount of metal will be welded on the journals and ground down back to stock diameter it shouldnt need to be rebalanced. The extra weight( if there is any)would be equal on all planes. Along with this idea is if you have a crank turned down .030 on the rods you don't rebalance so I wouldn't think you would have to this way either. Did I miss something?
