I believe this sort of thing has been talked about for years. Didn't Intel do something like that? This, for instance: https://www.nextplatform.com/2018/05/2

From what I remember, the problem is that there is a fairly large amount of work to get useful performance out of a hybrid like that. It's easier to just, say, learn CUDA and use a GPU than it is to have HDL folks work with SW. I have no doubt a system like that would be useful, but it would probably be expensive and limited to specialized, low-volume applications(like big FPGAs are now).
