Serializing anything to a plain PHP array

Hi,
I know this sounds weird, but the idea is to use serializer bundle to convert any data to plain PHP associative arrays. 
The use case: 
We are using \SoapServer working with Doctrine entities. There's no way to implement anything like "@Accessor" with plain \SoapServer. So the idea is to write a wrapper class, which calls the methods of original class and converts the result to plain PHP associative arrays with all the features of SerializerBundle. 

Does it sound good?

P.S. I've already started working on this https://github.com/intellectsoft-uk/JMSSerializerBundle/tree/array-serializer
P.P.S. I will also need to implement PropertyNameNamingStrategy described in https://github.com/schmittjoh/JMSSerializerBundle/issues/49
