Help making data pack

So i'm planning this bedrock edition behavior pack for 1.17 based on tikers construct, where it will use the smithing table to upgrade tools, armor and more. I have a friend who wants a java version of it in datapack form, so i was wondering if anyone would be willing to help convert it, I would give full credit and such.

Even if you can't help, I would be happy for feedback and recommendations for features.

I have things like armored elytas, upgraded shields, and so on (it's not as complex as tinkers construct but I was hoping to add more things, as it feels somewhat lackluster right now)

If you are willing to help me convert it to a datapack (once I am done) Please PM me
