I would personally be more interested if it were an autoloader. If you want to make a pump bullpup, I would suggest using a Browning BPS receiver or some such, it would load and eject through the same port, solving any loading-port-next-to-the-face issues. I think having the barrel on the bottom would help to control muzzle rise, again similar to Kel-Tec's RFB design. Best of luck.
