Write a couple sentences for each question

There is a technical difficulty with this, since a classic paragraph structure requires opening and closing sentences and these wrap the filling of interesting sentences that put the flavour in your multi-sentence sandwich. Idioms typically are observational or clever in nature, so don't make good closing and opening sentences. An all idiom paragraph would become an all filling sandwich that is a bit of mess to construct and consume.

Could we stretch your question a bit and allow declarative opening and closing sentences so we can layer up the middle with tasty idioms? If so, I suspect a fairly long middle could be packed in.

Another stretch could be to consider a block of dialogue equivalent to a paragraph (technically wrong since switching speakers creates a new paragraph, but we're stretching here). You could probably create a long banter of idioms between two speakers.
