I might have a sneaky way to do the cuffs... planning on a doublet after i finish my tweed argyll... maybe before since im going to have to wait for buttons...

I think your bigger issue is how much you want to deal with the pockets... i got what appeared to be a 42R rather than a 44L when i bought my doner jacket... upside was pockets were higher (so no moving them) downside was sleeves had to be lengthened (easier than pockets) and not enough fabric for gauntlet cuffs...

If you're normally a short, a long might drop the pockets below the cut for you... I dont think i've EVER cut the pockets on one of my suit jackets, so them being usable to me is a non issue...

Im guessing you might need to tailor the fit a little with a longer jacket, but if the lining is ripped out anyway that shouldnt be a huge issue (famous last words since im trying that tonight)
