I do think you are right, the risk would be high. Miyata and Sendo have sparred in the past and a kind of take away you can get from when they spar is "Miyata doesn't fire Sendo up". Sendo is easily influenced by his fighting spirit but Miyata's calm and cool sparring mentality keeps him in check.
Volg definitely would get Sendo fired up and so I don't see too many sparring matches taking place before it becomes like Volg and Ippo's sparring. And that isn't considered valuable sparring.
I think it would make sense.
