It should be quite straightforward for any decent machine shop. I would look to see if that exact same head is also available in 1 1/4" bore from the manufacturer. If so then you can assume the engineers have decided that the larger bore is acceptable. Make sure they reproduce the little chamfer on the edges of the bore and protect the outside from the chuck jaws, especially if it's aluminium.
