I try to keep it simple.

I like my feet, so good hiking boots for the trip are required.

I like to wade, so I carry waders (where I go the waters too cold even in the summer for me to 'wet wade') and my wading boots in a simple backpack. Fly vest and food, hydration, extra clothing, all fit in the pack.

When I get where I want to fish, I put on the fishing gear and fish. The hiking boots and shorts go into the pack, taking the space the waders/wading boots/vest used on the hike in.

When I'm ready to hike out, I change back. I don't like to hike in wet feet or clothing, so I always put on dry socks and change whatever got wet, for the hike out.

Only takes a couple of minutes.
