The style of the saddle isn't an issue for your horse so much as tree width, flocking, and saddle placement.
I don't see any reason you can't use a "saddleseat" saddle in a more forward position like a "normal" english saddle (agree with those who say sitting back in the traditional saddleseat position would likely not do well over a distance), but the saddle needs to fit your horse first and you second.
Is the seller willing to let you bring your horse and try the saddle on? Or can you make a wither tracing and take it with you to measure against that saddle?
