Then on the IP, drill 2 small holes on the left and right side of the whats left of that mount. Then on the fabricated piece do the same and tap a hole in the middle for the Idle Adjust screw. (Is it EXATLY 14mm?) and then using alan screws fasten that newly fab'd piece to the old and done.
So which idea do you support?

I like the #1 proposal because it is the simpler of the two and involves less engineering and risk.
My only advice is to have the machinist mill the top of the remaining portion on the pump so that it is flat and can accept the new piece.
Additionally, I can't tell from the sketch the size of the cap screws that the machinist is proposing to use. You would probably need two #8's as a minimum. #10's would be better if you have the space.
If you can't get #8's to fit, you are running too much risk in terms of strength. The big 14 mm thread can bend them right over if you are not careful.
The machinist must clamp the IP securely to do the work. BE SURE that he does not use any more clamping pressure then absolutely necessary. Most machinists like to torque the piece down very strongly. The pump won't tolerate this.
