I'm not aware of any manufacturer who is committed to providing a ChaCha accelerator or ISA extension, but it seems like it would be highly doable. Not sure what the minimum latency of a ChaCha double round is, seems like it'd be a couple hundred picoseconds, unless there's some sort of forwarding trick with the adders/rotations.
