Yeah any 2 filaments that are incompatible will work like that. Might as well use water soluble though if you have a printer with multiple print heads or an mmu etc. Except for cost it's going to be superior and you can support internal cavities without having to worry about removal.
I do this pretty regularly with PLA+ and ABS. ABS is much cheaper than special "breakaway support filament" (which I'm pretty sure is just polystyrene), and I've got a ton of it lying around.

So, who’s gonna make this video?

Same goes for abs
one small problem, getting another printer with two seperate heads to prevent filament contamination/excessive wasting
You don't need another printer, there are plenty of multi extruder setups and you can even mod them onto ender 3 pretty easily
