I think you would be hard pressed to find someone willing to do that project. Most would probably quote you such a high estimate as to run you off.

 

I know a couple people who are machinists and have access to industrial mills. I was concerned about the structural change in the extension. Ideas?

 

Another approach

The table seems to be a standard 27" deep.

Peachtree Woodworking has a cast iron router table extension with an insert in various sizes for under $250.00:

Use your grizzly extension on the left and a Peachtree with a lift on the right or vice versa, for a really nice wide surface.....Just a thought.

Router extension table

Personally I wouldn't and didn't when I bought an extension for my table saw. I ended up making a free standing router table out of my extension a Bench Dog Pro Max cast iron. In fact I made 2 of them.
I didn't like the idea of clearing off the router table fence and lowering the cutter height in order to utilized the full width of the table saw. I like being able to leave the router table set up then make any cuts I want on the table saw and back and forth. Just my preference however. Unless you are absolutely cramped for floor space I would not spend the $420 on the extension you are contemplating. Instead get a great Bench Dog 41" wide table with the proper plate already milled in.
