It looks like a good concept to me, but the router and cutter needs to be centered, not the gantry. I like the diagonal structure that makes the gantry more rigid.
That way the frame and table can be configured so the table can be moved forward and backward from the rear edge to the front edge of the table.
Likewise, the frame and gantry needs to be wide enough that the cutter can reach each of the side edges of the table.
