Is it possible to make a multi-display adapter as an independent project?
For a well done project? Very, and Expensive. You would need to source a proper Mini DisplayPort adaptor, then figure out how to turn a digital dvi signal to display onto two monitors while the computer only sees one. And if you want thunderbolt? Forget it. Outside of any conceivable student range or pricing. According to MSI, a huge manufacturer of motherboards, Thunderbolt would cost them $35 dollars to implement per board. And we are talking mass production price.

Simply put, not a trivial project, especially without experience.
