As a first attempt, I think you've got a good recipe there. I too have no idea what the rose petals are going to do for you in a beer -- floral for sure, but not sure if I'd want to be drinking the same smell as my soap. Other than that, go for it. Mugwort is pretty good stuff. So is sweet gale (which you have not listed). I use sweet gale just like a hop in my gruit ale. It's nothing to fear. It doesn't generate bitterness as much as a certain tartness and characteristic gruit flavor. Yarrow is also tart but also provides some bitterness. Expect your gruit ale to be tart. That's what I've learned. It is the tartness and herbal character that balances the sweetness in a gruit.
