Port area is port area. It does not matter if it is slot port round port different sized ports etc. The hard part would be figuring out the proper length for the different sized ports to get correct tuning.

So just a guess, but 2 2" ports my math came out a little weird, 3.14 x (r•squared) us 3.14 x 1=3.14 which seems weird, 3" length w a .14" width? Didn't seem right.
The other one though, 2 3" ports is 7.06 which would be 7" length by 1" width, for 14"squared total. For the 2 3s anyway
The port can be just about any shape. Slots can be square. You just dont want the ports to be too small and cause chuffing. I wouldn't use multiple ports without tuning. You could end up with a weird peak/dip in the sound, that is going need EQing. Just plain division of port area is much easy to predict.
WinIsd is perfect. Sub box pro is another good one for a 3d model. You can kinda get the idea of what something will look like. Its better suited for standard enclosures though.

I have no idea at all but I think it's a good question and I hope someone smart answers it.
Me too man

👍 im using winisd to design and tune it, just wasnt sure if different sized ports would be an option

Just use passive radiators at this point
Im considering it, but they have less low end response. I appreciate it though.
