A full convert of a map from avp2 to VMF. you'll be facing all sorts of obstacles, as avp2 maps have lots of triggers/ai built into them or the mapper has put custom textures/sounds on them.
if it does work? I can guarantee you.. the map will be broken. (As Dedit is a harsh reality)
There are avp2 maps made for the source on steam workshop.
I guess you could use them and give the author credit.
