Some thoughts:
1) Wireless HDMI almost always requires line of sight to work.
2) Multiple inputs to multiple TV's is either a matrix switch/extender config or you can use a IP based extender config with multiple transmitters and receivers (you would need to change a rotary switch to assign input to output for example). This latter would require a dedicate network switch to handle the throughput. Also, some video wall systems could be used as a matrix switch.
3) broadcasting from portable devices like a phone or tablet is easiest when you use cast on said device to a TV. I don't know of any gear that works as a extender transmitter AND wi-fi receiver.
And lastly, after 20+ years dealing with extenders I can say that God hates extender products in his house. Easily the highest failure rate outside of some Caribbean island with horrible-no good-really bad-electrical grounding. Regardless of whether it was built in 1780 or it's a new mega church.
4) Why are the existing wire runs a problem?
