One thing I'm looking for but didn't see on your web site would be a domed top for individual surface mount square LEDs.
This would be of benefit for folks like me who are using Neopixels in custom theme pin builds - something like this: http://www.thingiverse.com/thing:734182
But, something that is a bit taller to bring the light up high enough to be usable for GI replacements. Snap on or glue on, doesn't matter.
It would be very simple frosted molded plastic but something I'd immediately buy 120 of for myself. It would also allow you to expand to carry those RGB LEDs since you'd have a way to make them more usable for the community.
Thanks,
Raymond
