Help with alpha 20 mod

[jonsmith31415]

Hello,

as the title suggest I'm am looking for help with modding alpha 20, the only thing I don't like is the block upgrade path, so I was wondering if anyone could help to restore craft wood frame blocks and upgrade to wood blocks, as well as wet concreate, reinforced concreate, and stainless steel, or tell me how I could do that,

 

any help is appreciated thank you
