Jeff, Andrew etal:
1. I vaguely recall this subject coming up 10 or more years ago, with the conclusion that a tool called a "bypass lopper" beat saws. This Amazon ad
shows at least 3 companies producing tools that seem to be about $15 per inch of wood material to be sliced (1.5 up to 3 inch). Mainly designed for use in the field, but clamping on a bench should be fairly easy for many, and it might do double duty.
2. I really know nothing on this topic - just repeating earlier dialog.

I checked out one of our local farm supply places looking for a flat disk blade but now that it's winter all of those types of things are gone or put away. Impossible to find anything outside with all this white stuff on the ground. Looks like I have enough scrap for the frame.

It was to show a principle of slicing the fibres as the force of the blade was applied with as much rotation of the blade possible. How the dimensions are determined can be proven using a cardboard mock-up and leaves plenty of room for innovation relating to the features you mention.
