I discovered recently that IKEA actually do a deeper Billy that you can order online. I've seen them as deep as the Kalax. I used to work there and never knew. Might be helpful for the overhang
if they're the ones I'm thinking of (wide, but not very tall, good for large flat things - basically map drawers but not quite that big) just be forewarned that the drawers don't fully extend. (There are mods to fix that which involve doing some drilling and grinding on the drawer slides...)
