Here is one thing you can do.

Copy the image you want to multiply. (CtrlA and CtrlC)
Make a new 'Black' color layer and click 'add mask'.
alt-click the Mask icon, so that you can enter to mask edit mode.
Paste your 'multiply' images in the mask (b/w) , and then invert it.
You will have a black layer with your multiply material masked.
You can adjust opacity of that layer to find best looking image. (30~40%?)
If you save it as transparent PNG file, you are done.
