I have a really wide two cherries, but can I offer another suggestion?
Use an old/spare plane blade and epoxy on a handle to one side (or both sides). You can find old plane blades with good steel cheaply. They're easy to sharpen and you don't actually need all that much force when pairing.
There's a article from one of the magazines that's completely escaped my memory, but they used a rosewood "handle" on one side epoxied on with threaded inserts, then another rosewood handle on the other side that screwed into the inserts. Basically a rosewood sandwich with the plane blade in the middle.
Then they had a flush plane or a 2.5" wide marking "chisel" when attached.
