We planted several Empire Buddleias six weeks ago. The leaves are wilted during the day but perk up the next morning. I measured the moisture and down low in the ground, it's very moist but dry at the top. I suspect the soil as I tilled in Black Kow and peat moss since we have a sandy soil. The plants are just not doing well, and I was going to totally replant them and replace the soil with general potting soil. Is this a good idea?

Perhaps adding in some compost or fertile potting soil will help but you may also want to consider mulching the area around your plants. This will help conserve moisture, especially close to the surface.
