I know it's fairly common practice to use a jointing fence on a router table with a slight offset on the outfeed side. However, this just guarantees as straight edge, not a parallel edge. Also, you are limited in thickness to the height of the cutting bit.
Is there a reason why you can't use a fence on the left side of the router?
This would let you get the sides parallel, allow stock up to twice the thickness of the cutter bit (by flipping the stock over), and let you control the final width of the stock.
I've attached an image showing what I mean. Is there a problem with kickback? Given the direction of rotation, I don't think you have to worry about it grabbing and throwing your piece.
Thanks,
Kevin
