April Kisses - Eddie Lang

nixpix

I'd like to know how you'd approach playing the "Cadenza" on the introduction of April Kisses. It's transcribed in the Eddie Lang Modern Advanced Guitar Method, but pick direction is not given. The Gypsy Picking book has really helped my playing of Eddie Lang tunes, but I don't see how I can build up speed to match Eddie doing two consecutive downstrokes on the 5th string. Here's how I play it (excuse the poor tab quality). What do you think?
