of mod it with several 20W 650nm bars stacked, and a fiber output from a CuBr, so you have the tinyest highest power remote projection head

You'd have to get rid of the color wheel to get pure blue output. And you might destroy the DLP chip when you did that, because there is a "notch" in the color wheel with what looks like translucent glass in it. I think this is where they're killing the blue laser coherence so that they don't get any speckle in the final image. But without that, I think the raw laser power would kill the DLP chip.
Then again, if you just wanted it as a beamer, you could yank the color wheel, the red LED, and the DLP chip out of it and just use it that way. I think you'd end up with about a 1.5 inch square beam (with horrible divergence), but it would be bright as hell nonetheless...

and then you have the most magnificent adjustable focus pump source for your fresh ebay coherent dye laser
Don't forget that the stock power supply runs these diodes pulsed at 250Hz. So that's not going to work for any scanning effect.

Still, there's nothing wrong with using your own driver to power the diode array CW... That might work. So your experiments are not in vain. If you can get it working in blue-only mode, at least we'll be able to see how good (or bad) the stock optics are.

Does anyone have any suggestions on what angle anamorphic prisms would be suitable?
It's been done, but it gave really shitty dot quality, and divergence. So far, the best lens I have seen for them are the simple glass lenses AR coated for 405nm. It had the best profile in the end, and a good diveregence (IIRC <1.5mrad). The sock lenses gave it a massive dot size, so a large divergence, and it gave a large amount of artifacts around it (halos and stripes, etc)
