I haven't seen one, though I have never searched either, but it could be helpful to also look for 16mm reel - as that is the width of 110 film. there might be something, somewhere with that designation instead.
Failing a commercial solution, it is possible to remove the spiral from the wider-tubed of the two reel halves and glue it further down the tube. This depends entirely on which reels you have and what they are made of however, as epoxy doesn't work well all the time. As 110 film is much shorter than 135, you can use all sorts of scrap plastic and so on to support the spiral. Cut a long strip of paper, film-width plus a mm or so, and put it "in" the film channel to support the spiral until it is dried solidly.
I've a plan to modify a Jobo reel in this way for Minox film development, which is to suit a film width of 9,2mm. When that stays glued, and seems to work, I'll be making a post about it.
