I don't know if it would improve if you went back to the MWC, but you're not really competing with Utah since 2011. Here's the rankings before 2011 and since (247 composite scores only):
2005: Utah- 57; BYU- 61
2006: Utah- 56; BYU- 65
2007: Utah- 62; BYU- 43
2008: Utah- 61; BYU- 45
2009: Utah- 46; BYU- 55
2010: Utah- 42; BYU- 33
So the pre-2011 averages are Utah- 54.0; BYU- 50.3. Those are the players who are playing in the 2011-2015 games. Since 2011 it's been pretty different:
2011: Utah- 38; BYU- 69
2012: Utah- 38; BYU- 71
2013: Utah- 47; BYU- 66
2014: Utah- 66; BYU- 64
2015: Utah- 45; BYU- 65
2016: Utah- 37; BYU- 49
2017: Utah- 33; BYU- 66
2018: Utah- 34; BYU- 78
So the post-2011 averages are Utah- 42.3; BYU- 66.0. If we remove both teams low outliers (2014 Utah and 2018 BYU) the averages are Utah- 38.9; BYU- 64.3.
So the pre-2011 average BYU beat Utah by 4 spots. Post-2011 average, Utah beat BYU by 24 or 25 spots (depending on if you want to count the 2018 class or consider it an outlier. It's been a nearly 30-spot shift in Utah's favor since 2011. I don't know if that gets any better in the MWC, but your recruiting isn't really likely to get significantly worse either. You're not keeping pace with Utah in recruiting as an independent any more than you would in the MWC.
