Well, the question was: can you do analog designs? Designing your own transistors, not relying on logic gates library. That's what full custom means.
That opens the door to less conventional stuff, such as CMOS imagers, memories, RF/Analog designs, etc. Obviously the available space and I/O are going to be limitting factors.
Regarding Wi-Fi, I was thinking of some of the RF frontend for a project such as [1]. I am not extremely knowledgeable about RF, so that would be a learning opportunity. I imagine it to be mostly carrier generation and multiplexing, the higher layers are doable on an off-the-shelf FPGA.
That said, Wi-Fi is a simple target, but maybe not the most interesting one. That's the first full-custom application example I thought of.
