_CAN_ it be done -- I don't see why not.  The graphics portion might be
slow, since it'll be coming through a 9600 baud serial line.  
How easy would it be?  Well, Apollo provides source to emt in /sys/source/emt,
so you can make it accept any escape sequence you want.  You can also have
it start up in RAW mode instead of COOKed, re-configure the serial port at
startup, or even have it invert your screen and shut down the node.   :-)

Seriously, good luck to you.  I haven't played around with the graphics 
routines, though I want to eventually....
