Sandblasting talk

Just had a goofy idea —- thinking of adding a air inlet to my HF blast cabinet and hooking it to the exhaust of my 18 gallon vac. Then let the outlet of cabinet blow through a hose to the outside of the building. I would think this would eliminate the vac filter from clogging and the need for a dust trap.
Has anybody tried this ??? Give me your thoughts.
