power supply they provide, which is 12V @ ~320W.

Wow, that's stingy. The 'standard' mk2 pcb for 200mm2 is typically around 120W and is considered by most people to be under-powered. If you scale that up for 300mm2 you'd want 270W just for the bed, which doesn't leave much lee-way on a 320W supply.
These days a transformer can cost more than than a switched mode power supply. I used to build linear power supplies for all my projects in "the good old days".

but are there going to be any issues with hooking up 24V to this build plate?

Nope, there are only two pads for power (and some smaller ones for LED, etc.) and yes, it's only 1.8 ohm. My guess would be that having it be lower resistance would be a bit too much power draw for the power supply they provide, which is 12V @ ~320W.
I actually thought of a cheaper solution: A 24V transformer and a SSR, because why do I need DC anyway if it's just for the HBP?
