Wheels for 12mm stud?

I found the wheels I want and they fit a Honda S2000 which has 12mm studs.

They are 18x8 5x114.3 and +48 offset and 73.1 hub bore.

I am hoping to drill them out to fit 1/2 stud.

What do you guys think?

Going on a 67 Cuda Notchback, 73 K-member LBP discs up front and B-body rear without mini-tubs or offset shackles

shouldn't matter-if they're anything like the 5zigens on my Stealth, they use a tapered 'tuner' lugnut anyways, and not a shoulder-type lug.

edit-the main thing will probably be making sure that you get hubcentric rings

it looks like the studs are right next to the contour of the spokes. im sure it would work, but you might have to have them refinished after drilling. it would also depend on the lug nut style you are going to use. i dont think you could pull off a shank style lug nut because they need a 13/16 hole and use washers. a 45* or 60* concave acorn style lug nut is going to need a seat to sit in. 12mm=.47 inch. that is so little of a difference. with the right lug nuts they may just go right on
