I have come across the issue of wanting to use both two prepositions to describe a subject. This is not a common issue, judging by the lack of information regarding it.
This is an example of the type of sentence I am proposing:
A statue stood at and as the heart of every nation.
This sentence describes the location of the statues—at the heart, or center, of the nations—as well as their symbolism and importance. It may not be grammatically correct, but it eliminates the need to form a complex sentence, though the sentence certainly is complex in another way.
To restate the question, does the chain of "preposition -> conjunction -> preposition", as used in the above sentence, violate any rules of grammar or formal writing? As a side note, please tell me your opinion about how the example sentence sounds. It sounds fine and rather impressive to me, but I would like an unbiased opinion.
