Doubtful it would work. Anything is possible, but this approach would be my last resort. My first option would be straight exhaust.
1) Charcoal filters primarily useful on organics.
2) Acids require activated filters which are tricky.
3) Give-back of filters when turned off.
4) Wide divergence on quality and support of companies making this type of filtered hood…some good many bad!

Subject: [DCHAS-L] ductless fume hoods for acid digestion
Good morning all! I have to take a minute to get some additional opinions on a topic. I've been approached to provide my 2 cents on the appropriateness of using a ductless fume hood for acid digestion (preparing samples for analysis via AA). This would be for use in an industrial quality lab.
I have my opinion; what is yours?
