That's an interesting thought!
I put in a lot of little tweaks here and there to nudge it towards being platformer-friendly, like squashing the shape to make it more horizontal, or building vertical rooms before horizontal ones. I suppose if you could disable all those little things then you'd get something that's more top-down neutral, with the passages and gating intact.
I have no idea how well it'd work for top-down, though. I feel like it wouldn't really resemble a Zelda-style map at least, but it could probably be tweaked into one.
