I'm using the Feeds module, but I am looiking for the functionality the Feedfield module provides: declare multiple feeds on a single node, and have a parser generate the nodes from the feeds. Problem is Feedfield uses the core Aggregator, and I need Feeds functionality.
Can I reproduce such a behaviour with Feeds and any addon? How?
No, it can't be done right now. There is a issue that will eventually lead to development of such functionality, but right now, no can do.
