Yes it could.
You would want the top of the dovetail to be slightly less than the bottom, if that was the intent. IOW, to 'lean in' a bit. I'm not very well versed in dovetail design to say whether it is a common design element or not.
If it was, I would expect that both angled cutters would be generally available for quantity production. One for the dovetail itself, and one for the part to be dovetailed in place. Is that what is common in a production workplace???
