I do a lot of trail running and keep more stuff than fits in my hard tail bag. I keep a cable lock with me at all times and do what you mentioned. I have a cheap pair of boots that I wrap up inside my jacket. They aren't locked but they are out of sight.
I think the pacsafe 80 (80 liters) for about $80 could fill your needs. Not cheap but much less than any hard luggage. Rather than using the pacsafe for your saddlebags you could just use it by itself and lock it to your bike.

My next short term goal in life is to go to a triathlon on my motorcycle. Love to see how you hooked up your mountain bike.
I don't know! I don't know why I did it, I don't know why I enjoyed it, and I don't know why I'll do it again!
