I would re-think the 1x lumber. At very least you are going to have a tremendous amount of bounce and movement. Keep the decking flat on the joist. Pack the gap and put a trim piece over that bridges between the packing and siding. Or pack the gap between the siding and joists and the start the decking at the packing.

16" centers, the original deck was 24". If frame would have been salvageable, I would have just replaced the deck boards but the more I got into it, the worse it was. I'm certainly no expert in deck building but even I could see they cut as many corners as possible on the original build.
I'm using a Brazilian hardwood (Tigerwood). I already setup a test with an 8 ft. board over joists at 12, 16, and 24" to make sure it would work. At 24" there was a tiny amount of bounce/flex, at 16 and 12 it was completely solid, even with my fat a$$ jumping on it.
I tried out Tigerwood, Ipe, and Cumaru. I havent been wood working long but it is simply crazy how dense and heavy these south american hardwoods are.
The slope of the joists/decking worked out just like I calculated. I ran the calcs to make sure it would work out, but it's still a little surprising when it actually does
