Has anyone created a Helm source from the results of org-agenda?

Specifically org-tags-view I think would be a cool Helm source to 

configure where the headings that have certain tags could be displayed

by Helm.

I looked @ the code for org-tags-view and it's fairly straight forward - however, I think

that the function itself is tightly coupled between finding the results and displaying the

results.  In other words, there's no "easy" function that I see which would provide headings

that match a tags search that I could use as a Helm source.

I think I would need to copy quite a bit of code from org-tags-view into a different

function to create a Helm source.  Am I missing something?

Has anyone else done something similar?

Thanks,
