If you use multiple layers be sure to set the layers of fabric at maybe a 30-45 deg to one another. Not to over think it but try and spread the strength over large angles of stress.
If you make it and fill it so that it is perfect then you can use your rear cover as a plug to make a mold over it and start popping them out.
The foam adds a large degree of stiffness when it is enclosed in composite. If you decide to remove the foam you will be rewarded with a floppy mess.
