I don't think that is is dangerous. Both are systems basically low 
current 5V connections. Neither DIN-sync signals would break the 
optocoupler, nor MIDI would kill the transistor buffers at the input.

Also you always sould place a kind of selection, which of both inputs is 
selected. So there should be no error.
Only if the socket is used as output, it might be recommend to add a 
selecting switch.
