Fiddling with a few different ideas, in my head. Inspired by reverse-engineering the Quickstart rules for Exalted into a hack, cross-referencing the Koch hack, and applying it to L5R.
Draw a 3x3 grid on your character sheet.
Along the top, write "With Weapons", "With Words", and "With Spirits" in any order. The leftmost column will be your strongest one, the rightmost column your weakest one.
Along the side, write "For Honor", "For Glory", and "For Status", also in any order. The top row will be your strongest, and bottom your weakest.
Then write numbers in your grid like this:
"With Weapons", in addition to the obvious fighty stuff, also covers use of physical force and motor skills in general, as well as knowing stuff about bushi and warlords and whatnot.
"With Words" covers the obvious talky stuff, and also knowing stuff about politics and courtiers and nobles and geography and stuff like that.
"With Spirits" is for explicitly calling upon spirits and getting them to perform favors or grant you wisdom, but also covers resisting the influence of spirits, luck (the favor of the spirits), and various nifty esoteric lore, as well as knowing stuff about shugenja and other related scholarly things.
"For Honor" covers doing something somebody of higher status told you to do. Or doing something because it's the right thing to do. Or doing something that's obviously not For Glory or For Status.
"For Glory" covers doing something really impressive, especially if there are others watching. Or something that's obviously not For Honor or For Status.
"For Status" covers doing something that leaves you better off than you were when you started. (Handy if you want a strong self-preservation instinct) And of course, if something obviously isn't For Honor or For Glory.
Everything's opposed rolls, high roll wins. If the obstacle you are facing isn't a person, the GM will just pick a dice size arbitrarily based on difficulty. (I suggest d12 as a baseline: most of the time, if you're busting out the dice and it's not contested, it's because you think something is fairly difficult, and that'll challenge someone playing to their strengths, but not be unbeatable by an average-sized die.)
Bonus! To come with your character's clan, answer three questions. What animal is your clan named after, and why? What clan do the members of your clan usually get along with, and why? What clan do the members of your clan usually not get along with, and why?
