As for the angle, I've found when I want to make a good rounded edge on anything, the best thing to do is find a cup, plate, bowl, etc. of the right size and trace around the edge of it to make a perfect curve. While this may still leave the separation of the opening a bit low for your kilt jacket, it should prevent the "sharp-angled" look from which many converted jackets suffer.

Good luck, and I'm anxious to see how it turns out!
That's a good method for establishing a curve. The challenge comes when that desired curve intersects the lower/lowest buttonhole. While the pictured 2-button jacket appears to have a lot of "meat" available below the second button, OP's description of himself as "on the S side" implies he may need to have that jacket trimmed up significantly.

All guesswork, of course, but those buttonholes can really get in the way of a nice cutaway! I've toyed with ideas for "reweaving" so that I can cut right through one, but several other projects are ahead of that on the roundtoit list.
