Request: Better horse and saddle statues in TS4

Although I like severinka's horse model and the saddle, I find that there's not much diversity in the horse's sizes unlike real life. I was wondering if it would be possible to put game ready blender models like this www.artstation.com/marketplace/p/v98pn/horses-stallions-game-ready into the Sims 4. I'd pay for the model to do it myself, but I have no idea how to put it in TS4 and not screw up. (and knowing my luck with trying to mod more than simple clothing textures, I'd probably royally screw up) So is it possible for something like this to be done?
