Im in school at the moment for machining. So the cost of maching will be zero. And im a certified welder, so thats free also.

The reason im worried that a press fit will leak is because the stainless steel insert, and the aluminum housing will expand at different rates due to thermal expansion. Possibly making the water tight press fit, not so water tight. Thats why i would want to weld it. but that leaves the other side to rely on the press fit. I have heard of people machining aluminum sleeves to replace the stock sleeves on older 13b housings. But im unsure if this is ture and if it would work. If I could use aluminum, i could possibly make a sleeve that would make a water tight seal that would hold it...
