In your sentence, If I were [colloq. was] the king, I could have you thrown in the dungeon, there's no such reference present. It merely states that if you were the king (hypothetical present time), you could have someone thrown in the dungeon (hypothetical present or future time).
I thought you should have written something like this, so that your sentence could correspond to Snappy's initial sentences:
If I were the king, I could have had you thrown in the dungeon (at that time).
If I were a bird, I could have flown to you at that time.
Thanks for your clarification. Your question makes much more sense to me now.
First, please realize that I am not the author of the following sentence:
If I were [colloq. was] the king, I could have you thrown in the dungeon.

So I was focusing and commenting only on the parallel subjunctive/conditional construction: "If I were X, I could have Y." that is evident in both sentences:
wiki: If I were [colloq. was] the king, I could have you thrown in the dungeon.
Snappy: If I were a bird, I could have flown to you at that time.
Admittedly, the above parallel ends abruptly when Snappy introduces the prepositional phrase "at that time," which obviously has prompted your suggestion (which, by the way, makes perfect sense ) to make the adjustment to the wiki article's example (once again, not mine) "have had you thrown ..., etc."
It has passed a few months, but I am still confused.
1. Please let me know if my understanding is correct.
a) If I had been a bird, I could have flown to you at that time. (This is grammatically correct.)
b) If I were a bird, I could have flown to you at that time. (Most native speakers do not think that this sentence sounds right, because the tenses are mixed.)
c) If I were rich, I would have bought the new PC on sale last week. (The tenses are mixed but this is okay, because people cannot be rich one week and poor the following week.)
2. If the above 3) is correct, what about the following sentence?
If I were a bird, I could have flown to her yesterday.
