This is a great question - and one that is in essence about style. Unfortunately, when it comes to style, reasonable people can disagree. What some people find to be beautiful poetry, others may consider doggerel. I personally would not use this construction as my first choice. However, the thing about style is that it is so context-specific. Something that sounds odd when said in isolation may sound poetic and beautiful depending on what precedes and follows the sentence. For example, if a writer has already used "so" and "therefore" multiple times in a piece of writing, by using "and accordingly" for a change, he gives his prose some welcome variation. I would say that the sentence is perfectly grammatical, but whether or not it is in good style (1) depends on the reader and (2) on the context in which the sentence is found.
