Cool to admit when you make a mistake, I have made plenty in my day and have admitted to some but maybe not all of them
You should have room to get them out, I was able to even with a 4x100 conversion but had to trim a tiny bit of not critical material on the front knuckles, a very tiny bit, 4x108 should be pretty easy.
A machine shop is likely to want the tires off the wheels, mounting and dismounting tires is a bit hard on the beads, I would try to clean up the hubs and bores a bit first but that is how I do things, not what I expect others to do, just making a recommendation based on quite a bit of experience.

No worries expected with PCA, Chalon is a stand up guy for sure
