grammar - Subject–auxiliary inversions beginning with an adverb

I am interested in subject–auxiliary inversions when the sentence begins with an adverb or an adverbial phrase. If the adverb is not negative (for instance, "not only" or "never"), can we invert the usual word order of subject + verb?

For example, can we turn "It faded slowly" into "Slowly did it fade"?

Answer

Verily say I unto thee that the way I have begun this sentence is antiquated and idiosyncratic.

You could use it but you'd sound like Henry V.

Even if you modernised the language by saying Honestly am I telling you you'd still sound odd, a bit more like Yoda this time.
