badidea. The alignment will not hold.
When the alignment guy set it, he not only rotated the cams but the bolts moved vertically in the slots. So the bolts are who knows where. The second you loosen the bolts, even with the cams pinned, your alignment will move. Whether for better or worse, in cannot say.
Then consider what will happen when you hit a bump, or slam on the brakes.
And finally, how long will the bolts last when operating as bearings?
