I wrote about how I approach blockchains from a capability point on view a few months ago on LI, see here: https://www.linkedin.com/pulse/blockchain-revolution-decentr...

I'd be happy to discuss further in private (chat/skype), but my "professional muscle memory" tells me that the only sane way of looking at a piece of technology is through its capabilities. When CIOs look for capabilities that can be met by blockchain then finding a business case becomes straightforward, otherwise it will be shoehorning as you say.
