That's actually what got me into pipe smoking (again - I had tried it in the early 90s but gave it up as I didn't know what I was doing and quit in frustration).
You could shred tobacco leaves and smoke them straight in a pipe, which some people do, and it's not bad but a little one-dimensional in my opinion.
Another thing people do is steam the leaves to make a plausible pseudo-Cavendish. I've done this with some success. Straight, unflavored Cavendish is pretty bland, but takes flavoring well and is a good component in other blends.
What I usually do is add tobacco scraps to a Virginia-based flake. Happy to share my recipes if you're interested. Here are some threads on flake and rope technique:

I realize that the flake setup is somewhat elaborate, but it works :) Others on this board have produced some pretty respectable krumble kakes with less elaborate press arrangements (weights, clamps, etc.).
Making a rope is more within reach regarding equipment, but the technique is more challenging.
& of course, you don't need to make flakes or ropes; you could just cut leaves into ribbons and blend them with other tobaccos.
