i can pretty sure it can be arranged, the wall is a short distance from the city, but we could make arrangements for driver to take us out to visit the great wall during when our afternoon breaks, i also recommend you to visit tian'an men square and city while you add it!
i hope to have time to visit great wall when i am here, i always want to go there, i think it would be a real shame by came all the way in beijing and didn't make out the wall, do you think i have a chance to see it?
