Covering old rattle can touch ups

Here is my dilemma. I have a 1966 300 with Saddle Bronze metallic paint. I started buffing out the paint and to my amazement it looks pretty good over all. The problem is the PO used touch-up spray cans all over the car when there was a scratch or some rust. There are at least 6 different colors and none of them match.

I will eventually repaint the whole car but for now I would like to soften the bad touch-up paint. I read the sticky on paint and am an experienced sprayer (but mostly as a house painter). I have a HVLP and have sprayed 2 stage urethane on cars and one stage urethane on metal doors. I was very happy with my results on both, but the single stage was a dark green.

My question is would I be better off for blending in with the old paint using a single stage?

Here is an example of his handy work. Look above the L and slightly to the left. This is one of the lighter cans of touch-up that he used.
