WSO2 ESB - Configuring Amazon SQS as a Message Store

Is there a possibility to configure Amazon SQS as a Message Store in WSO2 ESB ? Using a Custom Message Store ?

I don't simply want to configure a SQS Connector but a fully integrated SQS Message Store able to be used by a Message Processor. If not, how can I consume my SQS Store on the ESB ? Can I have to write a Custom Message Processor which retrieve messages from the SQS Queue using the SQS Connector ?

Thanks in advance,
