Wow, I never expected so many responses!! A few comments:

1) I considered the pre-made stringer (including metal) but the rise
was too tall.

2) This will be an enclosed step, so the 2x8 will not be notched like
a traditional stringer. Won't this be strong enough? I was planning
on slotting each step into the side of the 2x8s, and finishing up with
a traditional 2x12 stringer in the middle.

3) Love the 3-4-5 idea. Cardboard sounds like a nice follow-up. Now
if only I could cut a straight line with my circular saw

I'd put this in the 'life's too short' category, and buy precut treated
stringers from the deck aisle at the Borg. At most, they will need a
little trimming to match the as-found conditions, and to make sure the
rise and tread depth are the same for all the steps.

Since most codes allow a riser height from 7" to 8" overall, what
makes you think the pre-cut stringers are going to be at the 7" riser
height that the OP requires? *If they are, say, 7 1/2", they won't
work, no matter how much "trimming" you do. *With a little careful
planning, cutting a set of stringers is a pretty easy project.
