AX11000-Nighthawk Tri-Band AX12 12-Stream WiFi 6 Router and WAX610 AP

I have a 18th century stone / plaster house thats about 5,500 sq. ft.  No wifi system has worked, including Xfinity Xfi with pods, at an acceptable level.  

Looking at the AX11000 but it won't be able to get the whole house and was wondering if I could integrate one or two WAX610 APs into the mix.

Will this config work?

Thanks in advance!
