There are several decentralized file storage projects: IPFS, FileCoin, Sia, Storj

Yes - but I don't want it stored. And the Miners of those file-coins don't get paid just to forward it.
I only want to transfer the file, with proof that the recipient received it, and a mechanism to ensure some payment to the router.

It's not clear why you don't want it stored. The file must be stored somewhere for some length of time, even if temporarily. You can encrypt the file if privacy is the issue.
Proof of receipt is difficult no matter how the file is transferred, but it easy to prove that the file is accessible by the recipient.
The nodes that store the file are effectively the routers and they get paid accordingly.
