A horses success at a particular task is a product of the training that they've had, in addition to their physical and temperamental traits. So if you want a horse that's a good trail horse, you'll look for one that is responsive, quiet and been ridden extensively on trails. Some show horses have done this. However some show horses might not be quiet enough, or have the right temperament, for a trail horse. Others might have the right temperament but have no experience out. So it's certainly possible to
I think it's worth considering why you like show horses so much. They'll likely have good conformation and paces to be successful, but you can get many horses that have both those things that aren't show horses. Beyond that, their look isn't "natural". They're fed specific feeds to maintain the right condition, rugged and groomed extensively. In the ring a lot of them are wearing make up and other coat products to produce the final "look". Kept as a trail horse they're not going to look the same.
The second thing is a show horse is likely to cost a lot, unless you get one retired for age or unsoundness issues, which may also cost a lot in upkeep.
So think about what you want, why you want it and then decide the best way to find it. I'd recommend you look for good training, temperament and soundness first. You can get this with excellent looks but you'll have to pay more for it.
