Not really. You could leave the holes but it will be ugly as sin.

What they generally do is weld the holes, paint the part that they welded, and then blend it in with the existing paint. Then they clearcoat the whole trunk and nose.

I just got mine done this weekend while I was in Montreal and it looks immaculate. You'd never guess that the holes were ever there. Not even if you put your nose right to the spot.
