The things you want to create is can only be complete when pigs fly.

I just read the above sentence on the internet, which is to demonstrate how to use the idiom when pigs fly. I don't think it is correct, because there are two verbs in the main clause, is and be. But when I check it in Grammarly.com, it turns out that the sentence is ok. So I need your help.

No, this sentence is not OK as it is.

The things you want to create can only be complete[d] when pigs fly


The things you want to create will only be complete when pigs fly

Are both grammaticaly correct, but not idiomatic. Also, they have slightly different meanings.

Neither option conveys the meaning of incredulity that you likely wish to evoke.

An idiomatic equivalent could be

The things you want to create will only be [possible] when pigs fly

or, possibly in a conversation, as "when pigs fly" is a rather colloquial phrase

That will only happen when pigs fly

as a response to them describing what they wish to create.
