Ever repaired a stainless water tank?

I just bought a '79 Alajuela 33 with a leaky stainless fresh water tank.
I've read (D. Casey, N. Calder) that linear poly has many advantages over stainless. I've pulled the old approx. 70-gal. tank, planning to replace it with a couple of molded poly tanks. I still miight.
But now I'm wondering if it's feasable to get the welded seams ground out and re-welded with the correct wire or rod and have a tank that will last another decade or two. I'd get it done by a professional weldor who routinely works with that material.
The SS tank was made to optimize the available space within the keel, and so holds a much bigger water supply. Re-using it will also avoid having to build in supports for a couple rectangular poly tanks. And 2 poly tanks would have 6 potentially leaky fittings between them.
I'd appreciate hearing your experiences or insights.
