The standard miter slot is 3/4" wide by 3/8" deep. Shopsmith's slot is narrower (about 23/32) and shallower than the 'standard'.

No, the Shopsmith miter slot is not standard. It is not even standard across the Shopsmith inventory. Some are slots only (no t-slot).
These are the dimensions that I use.

The miter track could be made wider, if absolutely necessary, by taking off just 1/64" on each side. This would make the miter track "standard" width (3/4") and would still work as a t-track. Shopsmith is not likely to do this (and maybe you should not) because the existing Shopsmith miter bars would no longer work (excessive slop).
A bit for the SS track?

I was watching The Dusty Woodworker make a T-track directly into a wood piece, instead of installing a metal track. He used a router bit for this purpose. He said he thought there were many uses for a T-track directly into the wood.
My question? Has anyone ever seen a router bit that would replicate the SS T-track?

Here is a drill press table that has a t-slot, and it's process does not require any router. I am in the process of making a similar extension table and fence for my band saw using the dado'd slot with a hardboard cap.

William, I don't think you'll find a T-slot router bit off the shelf that will match the Shopsmith T-slot in one pass. MLCS has one with the "T" portion that is 1/8" high, so you could match the Shopsmith slot with a couple of passes. Most of the others I saw were 3/16" thick, but one of those probably would do the job as well. You'd want to remove most of the stock with a straight bit before switching to the t-slot bit for cutting the slot. Alternatively, you could just remove the washer from the miter gauge so you wouldn't need to worry about the slot.

A keyhole router bit(maybe).
The bit that I have could cut a 3/16" 'tall' x 1/4" deep lip.
FWIW: The 10E/ER miter gauge bar is 3/4" x 7/32".
