Yep.

Nope. You create donuts around the feedthrough locations in the inner
layer. However, you've got no way of soldering them at all. Inside
layers work with plated through holes, and sometimes with homemade 4
layer boards, but it's awkward.

you will get a board that looks indistinguishable from the thicker
material if you do it right. If the original board was single sided,
then you simply etch all the copper off one board and use it only as a
thickness builder.
You don't see the gap between the boards.
