I'm not actually that sure stand-ups need to be converted anyway! I've rode CP's Mantis, SFOG's Georgia Scorcher and DMP's Shockwave - all earn a 4 star rating in my book. Yes, they do have some flaws, being noticably bumpier than other coasters out there, but can you honestly say they're that uncomfortable?
And, how many major looping rides have you went backwards on?! I rode DMP's Shockwave about 3-4 weeks ago, facing backwards... OK, so having a headrest in your face isn't exactly wonderful, but we all turned our heads sideways, and looked out of the gap. It was one of the most enjoyable & memorable coaster rides I've ever had, on a par with my first go on a big multilooper, and my first go on Kennywood's Thunderbolt!
