Is this aircraft plausible?

I'm thinking of constructing a flying machine in the comic story I'm working on. Since I'm not an aviation expert, I'll try my best to describe this aircraft and you guys can tell me if this machine is plausible.

The aircraft looks somewhat like a glider made out of lightweight wood (akin to the wooden hull of a boat), where the wings meet at the center, and there are two adjacent cockpits, one within each wing. Beside the cockpits, on the underside of the wings, there are propellers.

The idea is the pilots can get in the cockpits and constantly drive an internal lever that sets the propellers in motion. I'm assuming the wingspan will have to be long, but I'm not sure how long. I'm also assuming that the lever mechanism amplifies the work put in to pumping it, so it doesn't take too much energy to make the propellers whir. Furthermore, this aircraft would probably be pushed off a high altitude location, like a cliff, in order for it to take flight.
