I imagine you will say "read the female Thor before you complain that we just had a female Loki." And yet can't one just be annoyed by the overuse of any specific trope? If Spider man gets mindswapped again in four years I think people could complain reasonably that the original story is still fresh enough in the consciousness. And how many Thor replacements have there been lately? Six? Seven? More? Just seems tired all around. The stories may be good but the concept seems stale.
