Nice, I like it. I think I'm going to try that too.
I made a diy no-board, with a board from before the standard 4 hole disc binding era.
It has screw inserts all over the place, I just ground the heads off some longer screws. Now it's studded.
Lets just say you wouldn't want to fall face first on this thing.
But where the inserts are, is where bindings should go. But without the bindings, you can't stand in that designated area & ride very well without the nose dive bombing.
If I put a swallow tail on it, that should put me back in the sweet spot.
