Great ideas. I do like the funding model for BTS to support projects and to my eye there is no reason why integration work could not be part of that.
I am not familiar with the influential stakeholders of BTS but I'd suggest start by lobbying the witnesses?
Hmmm... do you happen to know where/how would I find out who the witnesses are, and how would it be possible to contact them all?
If you go into the bitshares client there is a "Voting" feature where you can elect Witnesses and Committee Members with your stake. It shows the top of the leaderboard (most influential) and most of them have a hyperlink which should have contact details.
