You have little to lose by trying, but there’s no guarantee it will work at all, even less work well.
I think you do best to have just two stations in a powerline network situation because the contention and overhead of contention control is much less. (Compare that to gigabit ethernet which is full duplex and switched so there is little or no contention)
You can connect a "distant" powerline NIC to an ethernet switch and plug multiple devices into that if they are close together, that works better than plugging in multiple powerline NICs.
Unfortunately new houses have circuit breakers that detect broadband noise caused by arcing. These are good for catching fires early, but will blow if you use powerline NICs.
Google wifi pucks work much better, in spite of the cinder block walls.
Anyways, I use a set of powerline adapters with a second wifi router at the other end because the walls in my house are very thick (the studs are covered in shiplap on both sides). The throughput is fast enough to stream video on the other end, but I haven't put it to any measured test.
In the summer, I often take the whole setup to one of the outdoor plugins, so that we have solid wifi on the deck. So it can work quite well. Whether it will in any given circumstance is uncertain I suppose.
(These weren't label-advertised speeds, these were the negotiated links)
