Sorry the commercial stuff isn't working out, i dont think you could ever match the quality of the Pi4 commercially. The fatigue factor plagues a lot of commercial designs.
I cant answer all of your questions but i can highly recommend building the Pi4 with the 2226. I personally think there is a huge difference between the crossovers but I use my Pi4 mostly for music. If strictly for HT use maybe the upgrade isnt cost effective, personal decision. Good luck and welcome........
