Good results? I don't think so, here are two other methods...
Recipes with dry leaveners should be baked soon after combining with liquid for the best results.
It'd still "work" but you'd get a low-rise densely-textured scone. Now, coffeehouses sell those all the time, but it's not a classic scone texture though ultimately only you can decide to what quality level you want to bake.
If you're looking to save time, you can:
* mix your dough, portion, freeze, and then bake the scones (no defrosting necessary) - but - they won't rise quite as high so again a more densely textured scone.
* or better yet, mix dry ingredients, mix wet ingredients separately, and store each in a container (zipper style plastic bag works fine). Then in the morning quickly combine dry & wet, portion, bake. If your aim is to save time, this method works well, especially if you use a spring-release ice cream scoop coated with vegetable-spray to portion the dough (makes for very quick work, portioning most any food, I keep them on hand in every size). From mix to bake it's a quick 5 minutes work, with practice, in the morning and a far better result for your effort.
