Mmm.. no, distress reinkers won't work to colour acetate, I'm afraid. They won't dry properly on acetate. Have you tried perhaps using Red Pepper along with a darker alcohol ink colour, like Plum or something? Drops of each on an inking tool along with some blending solution and blot it all over the acetate, should give you a nice mottled darker red overall colour?
You could also try colouring the actate with a deep red Promarker pen. They're alcohol based so will dry on acetate... though you won't really get a smooth colour, you'll be able to see the pen strokes, as it were.
It might be easier to look at buying red acetate, if such a thing exists?
