Is the Touch ID hole a similar size to be able to replace the digitizer with an iPad Air glass? Please let it be so!

Yes. Compatible ^^ Checked today

Hello Caleb - I ran into a similar situation here within the 1st few weeks of a new iPad. Long story short, the A1474 digitizer is compatible, but the button is not. The touch ID is synced with the ribbon and the mother board. The older iPad Air (A1474) button is not recognized by the newer iPad A1822. If the button is damaged there is no way to repair it at this point. The best you can do is not to tamper with it and return it to either Apple or an authorized repair shop for a new machine which will cost $249 if still under warranty. You can find those locations here: https://locate.apple.com/ As soon as it has been worked on, the warranty will be voided and you will not be able to receive the discount. When a solution for the button goes onto market, then it may be worth repairing this independently. Hope this helps!

Same touch panel connections apparently however the Touch ID button is reported to be slightly bigger, so old panels won’t be able to fit a new button.

Yes the iPad Air Touch panel is compatible, but you will have to reused the home button due to the touch ID.

Your question is a liftle confusing but for the the iPad Air 1st generation digitizer has connection that are different from all other model. This is not cross compatible unlike the iPad 3/4. The Touch ID is also different flex cables between each model. Let me know if I misunderstood your question. Hope this helps.
