Re: could omxplayer display non rectangular area ?

info-beamer can do that. It has the option to render videos on OpenGL textures. So you can use all kinds of transformations. The downside is that this is more GPU intensive and FullHD might be problematic. The feature is used for example in this magic video wall package to arbitrarily transform vid...

From what I've read nobody who has coded this type of system for the Raspberry Pi has released it as free software.
While I'm guilty of that too, the following exists and might be what OP is looking for: https://github.com/balena-io/wifi-connect

True seamless will be hard to do with a rpi just based on the processing power. That's not correct. My info-beamer pi software is capable of that.

Re: RPi configred as Access Point to configure Wifi?

If your beamer is a client: WPS is deemed insecure, many APs do not support it and wise admins disable it. If your beamer is the AP: some clients don't support WPS at all, eg iOS. Yeah. That doesn't sound too good. I figured WPS might be used as a signal to trigger starting the configuration access...

Re: RPi configred as Access Point to configure Wifi?

(Still, I'd prefer a button. Just a matter of taste.) I agree. If the Pi had a hardware button, I'd totally use that. I haven't looked too deeply into WPS, but I feel like there might be neat way to make the configuration interface toggle-able that way. Not sure though. Might be worth looking into.
