Oh I agree, mixing two different patterns together makes this incredibly difficult, and those two patterns aren't simple either. But I feel like it's at least giving you all the tools you need to figure it out. Should a DM want to put in a difficult puzzle to potentially skip a series of tough fights, this would fit the bill.
And this one is definitely the easiest to retool into an easier puzzle - change the pattern, or reduce the number of tiles you need to put back in place, or both.
Also, thanks for bothering to grab the alchemy symbols and copying that all out. That must've taken a bit of time.
