Trials cranks will do what you want while not needing to cut off the spider.
Actually it's been a while since I looked at trials cranks and now I see that they are available in BB30 with a Shimano splined interface to a freewheel. That opens up a lot of interesting possibilities for various DIY mid-drives.
