Of course, it's a good idea. Extract the game archive, insert pictures of new castles, redraw the units, come up with a few interesting campaigns, rewrite the music. Will you have enough patience? The plans are certainly good, there's nothing to say about that, but to implement all this, you need a lot of like-minded people and a lot of free time. If you decide to do it, I wish you good luck.
