It looks very interesting for me.

As our incubating experience, would like to recommend refer to the Proposal
Guide [1]
first to prepare such paper work and also find some mentors who could help
for further discussion, vote and other process.

BTW, other project's proposals are very great reference, and please search
the previous
discussion and vote threads in this general mailing list, you will know how
to process
next step soon:)


Best Regards!

Luke Han
