The perimeter of the 'box' must be exactly located, and look exactly like a 'mini-me' version of the original wake shape, with all its 'complications', and, exactly where a true boat-tail would terminate at 24-inches out. Every place where the outline 'turns' needs to be compartmentalized with a wall, in order to generate individual vortices which cannot contaminate each other ( simple, not easy ).
And no one can say what the performance of the 'box' will be compared to an actual tail.
The 2012 Coventry University modifications to the 1999 Audi A2 is the only semi-contemporary use of a box-cavity, and it's 'result' might inform any expectation as to performance.
Should be interesting!
