Yes! You can do that, but run your beer line(s) through a 3 or 4 inch open PVC pipe, then mount a small 12vdc fan on the freezer side blowing into the pipe. Wrap the pipe with insulation tape to prevent condensation drip. This is basically how commercial bars do it.
The idea here is to keep the beer lines cold all the way to the tap. Place your CO2 tank OUTSIDE the freezer and be sure to add a temp controller to prevent the freezer from actually FREEZING your beer.
Also, at the base of the tap you can add a T fitting to allow air to flow through the pipe. I suggest restricting it down using subsequently smaller reducer fittings or just a cap with a few 1/4 holes in it.
