What is the expectation from doing this? …
Something a little more blurred/softer than the original, taking up more disk space and RIP time for no practical gain and benefit?
Or are you expecting the image to actually look better than the original?
Are these raster logos or raster photo content?
Enfocus PitStop Pro 13 has two bicubic resample options, I have not compared them to Photoshop though (however my guess is that it does not really matter).

My solution is a bit out of the PDF realm in that in my opinion Adobe products are the last place to do this. I perform this task daily in the large and grand format world. I take the PDF and extract the image in any way that suits, open it in Corel Photo-PAINT and export for Photozoom Pro it's a free add in in X6 and X7 and up sample the image there and save as a TIF. The end result in terms of quality depends on the quality of the original and how far you increase the size. A great image at 300 DPI can be enlarged in most cases 300% at 300 DPI. Photozoom Pro can also be bought as an application itself.
David, once you have the image resized using the “secret sauce” of Photozoom Pro, then what? How do you get the image back into the PDF?
