Are you looking for a nice job, or just a durable job? I really don't know how this would be done super nice, without going the whole hog of strip and redo.
As far as how to do it and not kill yourself. You have to get rid of enough chrome to allow the heat affected zone not to boil it off, those of very bad fumes. How much that is will depend on your method of attachment with something more localized like tig the heat zone will be smaller.
One feature of many forks and stays is that the reduction of diameter parallels an increase in wall thickness, so if you were to abrade off the chrome without digs and cuts into the surface, the mere use of an abrasive would not be significant, given the wall thickness.
I'm mostly into the front brake being a disc. And I would probably just buy a front fork with the tab attached.
