Yes, it can be made to work fine. The trick is sealing the box. Fuel lines are easy, as you can install fittings that have the appropriate threading on each side of the carb box wall, and seal with RTV or a gasket. Attach short fuel line hoses on the inide, the regular fuel lines on the outside.
The trickiest part in avoiding leaks is the throttle cable. I have found that using a tight rubber grommet works fine, then you put the throttle cable end on AFTER you push it through. RTV the grommet and it will still leak minimally, but not enough to impact your enjoyable boost.

You need a holley prepped for blow thru, and a good bonnett. A comlete enclosure is not needed. http://www.csucarbs.com/Products.html , that is a bonnet. Very simple to use.

Blow through carb mods are best left to the Pros and are not cheap. I'm going to start with a carb inclosure because I don't have the $$$ right now. You also need to consider that 7 lbs of fuel pressure and 7 lbs of boost = 0 fuel pressure. Your going to need a bigger pump and a fuel pressure regulator that is boost referenced.

The Carter/Edelbrock AFB can be used for blow through. Studabaker used a Carter in the Avante (I think that's right) somewhere around the late 50's / early 60's. It was blow thru turbo and one seriously fast car in its day. I don't know if anyone has tried the AVS/Thermoquad carbs, but I don't see why they wouldn't work if the AFB did. The plastic body on the thermoquad could be an issue maybe?
