Provided detailed instructions, why not? I would trust it 5*.This might be heresy, but I'm thinking of getting a cossack jacket made with raglan or semi-raglan sleeves. I see a few varsity-style jackets listed with raglan sleeves, so it seems like something they can do.
Do we think it would be a bad idea to request something more complicated - a semi-raglan sleeve like this vintage jacket, with a more traditional front and a raglan back to the sleeve?
EDIT: bad idea meaning it's not something they typically offer, so there's a greater chance of something getting lost in translation?
Assuming you can find a suitable leather (e.g. the pull-up HH). Buttons will probably be different.
