Well, maybe, maybe not, but I don't think they'd do better with today's camera, and I don't think any camera will make your shots better than what they can be, except... the one that'll make you go out and shoot
I'm sorry for this vague answer, it's not that I don't know cameras I have like 15 of them, I could pick one good camera that I know on the market and tell you that it's a great one, but today we are lucky to be in a time with many new types of camera being released, that produce different way of taking pictures... Reflexes, compact, mirrorless cameras, rangefinder, pick your favorite!! I know people who spent a lot of money on a great camera and en up taking pictures with their phone, I know people who collect analog rangefinders and end up using more their dslr, so... hard to give you a good and precise advice!
