Config w/multiple Wifi adapters?

My understanding is it's now supported through the kernel right?

Don't know, sorry.  Back in August 2022 a PPA patch was necessary but it worked.
The kernel has had updates since then but without putting the hardware and kernel together it's hard to say if a given bit of hardware is supported.
Running a live image is one way to assess your hardware but there may be some tweaks needed for a fully installed set up.

Using multiple live adaptors on one system is possible in theory but has limited practical use for a desktop or laptop.  If the adapters connect to the same network, priority should be set for primary, secondary etc so the system uses the highest priority one that is up.  If on different networks all adaptors can be active and the routing table decides which to use.
