Hi Ioan,
It is doable.
You just have to make sure of a few things first.

1. Board stack-up is symmetrical
2. Step and repeat allows even number of images
   (copper balancing)
3. Blind or buried vias add complexity (orders of magnitude)
4. KISS is best. The simpler the better.

I have requested flip image panels to reduce costs, warpage and
process times on many PCBs throughout the years. It works, but
you should spend a little more time in verification and probably
only use with simpler MLBs.
Hope this helped,
FNK

Now I got all mixed up.

I'm mainly talking about multilayer boards. Basically small piggy backs, but
MLBs still!

Is it doable or not?

And, of course, thanks for the input, Dennis, Jac, Robert and Eddie.
