If starsan is effective as long as the Ph stays low enough, could I acidify old starsan by adding the lactic aid I already have on hand?

hmm...i would just use the product the way it is meant to be used.it's not that expensive

Short answer...no.

You could re-acidify using sulfuric acid too. Catch is that you loose the important part and that is the food grade quality. Starsan when mixed to the correct proportions is a no rinse food grade sanitizer. If you go outside the lines sure it may sanitize but is it still no rise or food grade? Big risk for a small gain IMO.

I don't remember my chemistry well enough, and I don't feel like researching it, but there may be issues with even getting down to the original pH depending on the strength of the lactic acid.

They recommend adding more full-strength StarSan.

This is what I do...it's been a long time since I mixed up a full batch.

I had a feeling it wouldn't work. So its the balance of acids that makes it food grade?

I don't think balance has anything to do with it. I think most pure acids would probably be considered 'food grade', it's more about the strength of the acid. Read through this if you really want to know: Acid dissociation constant
