Question 1 Fly wheel 2 PP thread bad

Hi guys, went to reinstall PP on flywheel & Murphy showed up on last bolt! Per 17-20’lb torque spec last bolt stripped thread in flywheel! I know all the options. 1 Different flywheel w/o prob. 2 Helicoil. 3 weld redrilled retap. Or my solution as I have a lathe I went to a 3/8”-16 tap/thread & drilled a concentric hole in the 3/8”-16 bolt to remove weight till same weight as 5/16-18 bolt using balance scale to achieve same weight so it should still be balanced. I don’t like Helicoils. Didn’t wanna heat up flywheel w weld! Don’t think I need new flywheel! So that’s what I did. Engine still out of car. Don’t beat me too much but what do u think of my solution?
