So you wouldn't be starting from an existing table saw?
It should be doable, most likely it's just the need isn't there for it to be a common thing.
I've definitely seen saw blades on huge 5+ axis routers cutting large panels, but that's something a bit different.
Setting the blade angle would be the hardest part I'd think. Getting the pivot in the right spot.. What do you plan to use for the blade arbor?
