It is possible, although abstractions are quite different. For example
I use the following xml which is compiled with "swfmill simple
assets.xml ../lib/assets.swf"

<?xml version="1.0" encoding="utf-8" ?>
<movie version="10">
	<frame>
		<library>
			<bitmap id="mypackage.MyImage"
				import="assets/gui/images/myimage.png" />
			<font id="helvetica-neue-heavy"
				import="assets/fonts/HelveticaNeueLTCom-Hv.ttf" />
		</library>
	</frame>
</movie>

Since Flex does not have a facility to "fuse" two SWFs together, you
will have to load the swf compiled by swfmill at runtime. However,
from then it is pretty simple - load it on the fly into the same (or
different, how you prefer) application domain and get the class
definition:

var MyImage = flash.utils.getDefinitionByName("mypackage.MyImage");

var img_obj = new MyImage();

You can also try to include a source code along with your app which will:

package mypackage
{
     extern class MyImage, extends flash.display.BitmapData
     {
     }
}

If you are loading into another application domain, use
ApplicationDomain.getDefinition in the same manner.
