I've made this change on two or three older road bikes. Yes, it can be done, but here are some potential concerns. The front axle, especially on your older Huffy, is probably a thinner diameter than the hollow, QR axle. That means you may have to bore out the fork ends in order to accomodate the new axle. Additionally, you will need to buy two new axle cones to hold the wheel bearings in place. You may have difficulty finding new cones with the correct bearing seal size to protect the wheel bearings. Each wheel is different and you may or may not have this problem. When replacing the rear axle, I've never had a size diameter difference between the solid axle and the hollow, QR axle. However, in one instance the threads were not the same so I had to purchase new cones. When replacing the rear axle, be careful to note the postion of the spacers and chech the width of any replacement cones. It's important to line up the rear cassette/freewheel correctly with the deraileur. In my case, I had to retune one of the rear deraileurs after the change.
