Like my trusty 70 D 35, you can't make old wood. So no, they can't make a new D 25 sound like an old one. What they can do is make a new D 25 sound as good as those old guitars were when new.
Should you be willing to commit to being "under water" by buying an old D 25 likely in need of a neck reset, frets, and who knows what else, you'll have a satisfying guitar with a great neck. Same can be said of a D 35 or a D 40. I doubt you'll like anything better you could buy for $1600-1700.
There are quite a few older guitars you could buy and fix that would equal or exceed the cost of a new one. Bryan Kimsey, modder extrordinere, has a recent video of a 74 D 28 he said would have about $3,000 invested in it. It sounded great, and I'd rather have it than a new one. I guess you are addicted or not to old wood.
