Could I hook a 2011 MacBook Pro 15" with Radeon hd 6750M ... To three full hd displays? And if yes, what hardware is required

There are USB to HDMI adapters but performance is only okay over USB 2 and running two at once (plus a DisplayPort to HDMI) likely won't work well.

The only thing I can think of is a Matrox adapter: On paper it should give you 3x HD, but it runs at 50 Hz due to video bandwidth limitations. The 2x HD runs at the full 60 Hz.

So yes you can, but you should consider a newer machine. Even if this works, the Mac will really struggle.
