You can clear the path for courier's rasher as well, I did, the only difference is that you don't have the dream gate. Going through blasted steeps you don't need to do any serious platforming, while for the flower you have to traverse queen's garden. Also, the flower is one hit and you are out, for courier's rasher I took to hit and passed on a non cleared room by accident and still did it first try. The time limit is a bit scary, but it's still not that tight.

Edit: I already have the faydown cloak tho, that made it easier
