In 1978 I got an order for four 24 inch tall letters to be cut out of 1/2 inch thick plate aluminum.
All I had at the time was a Craftsman 14 inch woodcutting band saw. I used a 4 TPI skip tooth blade in that saw and cut out the 4 letters. It was slow going and I had to do a lot of filing to smooth the edge, But it worked much better than the jig saw and I made a grand profit for a week's work. Which was pretty good pay back then.
So, yeah it will work, you may have to change pulleys, blades and get new tires afterwards.
I think you have to weigh the value/need of the project vs. the cost of a few replacement parts or the cost of a saw made specifically for metal cutting.
