For the maple leaves, you could just cut out each side as a whole. Then outline each leaf with a satin stitch and sew in the leafs veins, instead of cutting each one out separately. That would also work for several of the design elements, the ribbon on the bottom being one of them.
You might find a fabric with buffalo heads on it, so you could just cut one out.
You might ask if any member has a design for their embroidery machine that might work for the pearls...something free standing like a applique...that could be sewn down and would be more washable than pearls and it would look more 3D too. Maybe for the crowns jewels, too.
I can't wait to see and hear more ideas for this... I love the story behind this quilt.
