IPFS - Arweave bridge plugin

[wackazong]

I am considering building a plugin for rust-ipfs that allows to use Arweave to pin content. The idea would be as follows:

1 Convert content into CAR format
2 Store the whole CAR file on arweave and tag it with the root CID)
3 rust-ipfs would then pin selected CIDs and retrieve them from arweave on request

Which CIDs to pin would need to be defined in some kind of storage where rust-ipfs would look up whether it is pinning this particular CID. I have not yet had a look at the code but I expect that there is some kind of storage available for this job.

What do you think? Would that be possible at this point of development? I would need some pointers to get started.
