We are third now, but some teams (Alabama) will close with a lot of high end guys. The last time I did the "what if" thing on 247 and added all of the guys you mentioned, we were still at 3rd and at a number that would not have been third in any of the recent classes.
I just redid the class calculator and adding Parsons, Oweh, Smith, Walker, and Enis we end up with a 247 composite score of 288.53 (up from 263.08 as of known verbals today). In 2017, the 288.53 would have resulted in 7th place, 5th in 2016, and 3rd, 4th, and 5th in 2015, 2014, and 2013 respectively. So, based upon the average here, we should finish around 5th if we get these guys (or most of them) and somewhere around 10th if we don't add to our class.
