If it were mine, I would drill it out to the next larger size, which is most likely going to be an SAE size. I would paint the bolt head as a reminder that I'm gonna need a 9/16ths (or whatever) wrench on "that one". Maybe even use a magic marker and write the wrench size somewhere nearby on the mounting plate. I can't imagine a helicoil being as strong as new threads in virgin steel, though I don't think strength is as critical as the helicoils' tendency to come out when you remove the bolts. Either way should work fine.
