I would be in for 20- *if* - I knew what the final product would look like. The snag is- I'm sitting back waiting to see as I've played with these things a number of times in the last 2ish decades I've had them. I've messed with OEM, blank, reproduction, 3d printed, screen printed, vinyl overlay, adhesive sticker. They all have some pros and cons.
For me to jump in- I'd need to see the final artwork. I'd also love to see what the plastic might turn out like. No judgement on anybody involved- it's just a little difficult to make the choice just yet. If I grab 1-2 as a trial- what if they're good and I need more and cannot get them (nothing will match)? If I grab 20+- what if they're not?
Manufacturing is pricey- so as far as the price goes- I'm good with it- if it meets expectations.
Maybe have a lesser option where you can sell blanks? I know people would love to have that option.
I'm keeping an eye on it. If things don't pan out- I appreciate the effort that went forward. I know where at least 6-8 E2s are that don't have anything and I know there are probably other people with cracked/missing translites. Would be cool to see a solution pan out!
