You just pound /glue a small wedge into the gap, since no one will notice discontinuities in end-grain. However, I can also imagine a bandsaw jig that clamps the bridle piece to an inclined plane till you get the angle you want. (Contrasting dowels will look nice! Dowel-makers are stupid easy to make.)
In the US, my emergency room bill (just stitches thank god) cost significantly more than the $900 smallest Sawstop.
