Trust me, I'm all for experimentation. I do it all the time - that's one of the main reasons I got into homebrewing in the first place (I will
brew that truffle/saffron beer I've been planning one day). I have learned through much experience, that you are much better off starting on the low end of all the specialty ingredients the first time you brew something experimental. It's far easier to taste something and say "I could use a little more of "X", and a lot more of "Y", and "Z" isn't really doing anything at all", than to drink something that is just a loud shouting match between different ingredients. A) Because it will more than likely be drinkable and B) if there's way too much of an ingredient it's going to be hard to tell how much less to use, if there's not enough it's a lot easier to ballpark how much more you need.
I know you aren't looking for anything to be subtle, but you're much better off easing up to it. Nothing wrong with a bold beer, but you're still going to want some balance if you intend to choke down more than a few gulps. I'd say keep the cherry smoked malt in the 15-20% range, skip the turmeric, and go easy on the mustard (rye should be fine as it is). If you use caraway, keep that low as well.
Of course, if you know you're only going to brew this once, are fully expecting to dump the batch, and just want to roll the dice, then give it your best guess. Tell us how it works out. I doubt I want to taste it, but I certainly want to hear about it.
