Ambitious 1st diy 3 way ceiling build looking for suggestions

I looked at buying typical ceiling speakers for a good while and finally decided I'd like to build some much better. Mainly because I don't want downward facing speakers. I'm making two for my living room and one for the kitchen that's parallel with no wall between. Currently have no system since moving in and TV speakers have finally drawn me mad. For now these will be the only speakers in this setup. The old lady believes in walls next to TV/fireplace will look bad..Hopefully can change that and eventually turn these into atmos speakers possibly. I have yet to see a 3 channel atmos speaker however. Still worried about how it will sound for now, but I'll take stereo over TV speakers any day.

TLDR: First crossover/speaker design looking for feedback to improve now before building. Parts have all been bought, but can still be returned. Powered by my Denon AVR-X2200W. Still debating two versions of my LR speakers and looking for suggestions.

Still have yet to figure out speaker grills, but here's my main questions.

1) Should I make these boxes taller/shorter? I have room to make then 20" tall
2) Do crossovers look decent on paper? Can I improve any? Not too sure on the kitchen design with the two 4" drivers.
3) Still debating on porting them? Any suggestions? If so would it be best to port into the room or into attic?
4) LR v4 or v5?
5) Polyfill them? Or just do one and then decide?
