In case others were curious, I did exactly what was mentioned earlier to enable playing my accounts on my iPad.
Created Apple ID B and Apple ID C
Logged into Apple ID B and Game Center B and restarted the game
Allowed the intro steps to play until the "Have an account" button appeared
Opened the game on the tablet using GooglePlay ID A
Retrieved a code via the "This is the Old Device" button
Enetered that code on the iPad with Apple ID B
Allowed game to "DELETE" the Lvl 1 intro game started
Logged out of Game Center B (it's not necessary to completely change the full Apple ID account each time, just the Game Center account)
Logged into Game Center C
Opened the game and allowed it to run through the intro
Repeated Steps 4-7 again with Game Center C and GooglePlay ID B
The game can now switch in between both alt accounts on the iPad by signing in and out of Game Center
Can also still play the alts on Android devices as well
Could probably switch in and out on my main device and Apple ID, but I'd prefer to just leave that as-is
The setup process was a little cumbersome, but for someone like me who is trying to manage multiple accounts, being able to do this on a device that is more familiar to me is a Godsend. Cheers!
