That would work but very poorly. It's amazing what happens when you go that deep a blue and into resist. Glass that is perfectly clean for red light becomes totally streaky and messed up beyond imagination. There is no way you could contact something into resist and it not be very dirty and full of stuff that shouldn't be there.
Plus, index matching is pretty much impossible. There's nothing that'll work for both materials, silver and resist.
I'm sure that if you tried hard enough with 17mw you could get something but it would be a very low quality, dim, dirty hologram. Even the smallest speck on an embossing master is reason for it to be rejected. I recently had a job rejected and had to reshoot it. Some of the art was 4/1000th of an inch out of register. Not much but it was right there on the surface. When the holograms are coming off the machine by the thousands if there's a defect that's all your going to see after a while. The same speck in the same spot over and over.
The masters have to be perfect.
