Sure. Paul Roberts has sold more rebored doubles than anybody I know of. He rebored, rechambered and reproved many .400/.350 and .350 No. 2 rifles to 9.3X74R. Another common rebore is .318 Westley Richards to 9.3X62 rimless, an increase of .037". The .450 NE to .470 NE is also common, an increase of .025". Going up .036" to .411" shouldn't be a problem. Most, if not all of Paul Roberts' (J. Rigby; J. Roberts & Son) rebores were done in the US by Cliff Labounty. The special machinery he made for reboring doubles went to Jim Dubell, who is the only one in the US I know of who can do it.

The issue is remaining wall thickness, and you need to make sure you have enough. In any event, it would really need to go back to England or Europe for re-proof. I know where there's a .475 rebored from .450 that blew up recently with normal loads. It had not been re-proved. Use of monos in a rebored double would be a really bad idea.
