There's a well-known blues outfit in London called The Delta Ladies - they're actually two guys in drag playing guitar and fiddle plus a percussionist.
The percussionist sits on a stool holding a large djembe under his left arm, and he has his cajon on an angled stand alongside him to his right.
He routinely plays the djembe with his left hand + the cajon with his right hand + various bits & pieces with his feet. It doesn't just look good, he's also a top-notch percussionist and his set-up allows him plenty of variety.
