yes.

Can the resulting document be opened with Illustrator or Inkscape?

Essentially, I open the two EPS images as input streams then I call
PSImageUtils.renderEPS for each of them using the same PSGenerator.
here is the code:
ImageManager imageManager = new ImageManager(new DefaultImageContext());
ImageSessionContext sessionContext = new DefaultImageSessionContext(
imageManager.getImageContext(), null);
//image info for the center and border images
ImageInfo centerInfo = imageManager.getImageInfo("center_image.eps",
sessionContext);
ImageInfo borderInfo = imageManager.getImageInfo("border_image.eps",
sessionContext);
//input streams
InputStream centerStream = new BufferedInputStream(new
FileInputStream("center_image.eps"));
InputStream borderStream = new BufferedInputStream(new
FileInputStream("border_image.eps"));
OutputStream result = new BufferedOutputStream(new
FileOutputStream("result.eps"));
//border image and center image width and height
int borderW = borderInfo.getSize().getWidthMpt() / 1000;
int borderH = borderInfo.getSize().getHeightMpt() / 1000;
int centerW = centerInfo.getSize().getWidthMpt() / 1000;
int centerH = centerInfo.getSize().getHeightMpt() / 1000;
//the viewport and bounding box dimensions are equal to the border image
width and height
//because the border image is bigger than the center image
Rectangle viewport =
new Rectangle(0, 0, borderW, borderH);
Rectangle bbox =
new Rectangle(0, 0, borderW, borderH);
PSGenerator gen = new PSGenerator(result);
//I first render the background image
//note: even when I try to render the border image only, the output file is
still not a valid EPS image
PSImageUtils.renderEPS(borderStream, "", viewport, bbox, gen);
//new bounding box with the center image dimensions
//(I believe the viewport should stay the same, I'm not sure)
//(borderW - centerW) / 2 <--- this is what I came up with to center the
image,
//I used this formula when I worked with other image formats
bbox = new Rectangle( (borderW - centerW) / 2, (borderH - centerH) / 2,
centerW, centerW);
PSImageUtils.renderEPS(centerStream, "", viewport, bbox, gen);
