@bobhaugen you can quote me. I wish I had better things to say. I see that thread. Best way to do it I think would be to make servers bridge between the spaces. Otherwise I think it is fine to manually quote & relay messages; we have done this for email ↔ ssb conversations. I recommend to include a link to quoted messages/threads. So for quoting a ssb message, if you include the message id (or a ssb-viewer link) then readers can find the original message on SSB to find the conversation here too, if they want to.
