Tiles can be placed in the foreground and background: background is always non blocking. Background and foreground scroll together. To simulate a forest, you can have a tree in the background next to a tree in the foreground and set the player between the two layers. This way, it looks like the player's walking between trees. As for speed, it's alright - although the game's on a 60FPS lock, I can still get around 30 on an older system (200Mhz).

Sure, it's possible but why bother? Graal does it already with drawovereverything images, and that does a pretty good simulation of layers. If there was a top layer than it wouldn't work with the current tiles so it'd be lots of work to put lots of transparency bits in all over the place. We can do all we need to right now anyway.
