Looks like I've gotten us a temporary stay of execution! They emailed me back this morning. First of all, they only made a bezel to test the color and not the plunger (he said that they stopped after he couldn't get them to light properly). So...he has asked the injection department to make the plunger and assemble a few complete samples for me. The samples are going to be blue, but it should give me a good feel for the translucency.
While not a total victory yet, it was a major step forward. I also pointed out that people are able to successfully light their non-translucent buttons, so a translucent material, polished or not, should be no problem.
Keep your fingers crossed. Once I get them (and I have a feeling it'll be a little while yet), I'll post some lighted and non-lighted pics. I have some of those brighter-than-the-sun blue leds from modsthatglow.com, so it should give us a good indicator if they are lightable or not.
