Merging Arduino shields.

Hi all.

Lets say i have a project using 4 of arduino shields like ethernet, lcd etc. and i know how to design and make a pcb.

I think we can find all of their schematic on internet.

Is it possible to merge them on a single board? What would be the potential problems?

Thank you.

Nearly anything is possible if you're starting from scratch.

What would be the potential problems?

Running out of pins (or pins of the right kind). Running out of timers. Running out of SRAM.

Can you please explain this?
