That would have been a good idea: Bringing the Princesses back from Tartarus to use as extra leverage to convince Twilight to surrender the Alicorn magic would have made Twilight feel even more pressured to decide what to do, now knowing her fellow Princesses were Tirek's prisoners alongside her friends and Discord. It would have also made it so the Princesses would have to bear witness to Twilight losing their Alicorn magic alongside her own in person, instead of sensing it from in Tartarus, thus leading to their dulled eyes when we see them right before they get their magic back upon Tirek's defeat and return of the stolen magic.

Remember: Twilight had no idea what became of Celestia, Luna, and Cadance after she left Canterlot and returned home to Ponyville. Had Tirek chosen to show Twilight the other Princesses' fates, or bring them back to use as extra hostages, it would have put Twilight in a more difficult position with her decision: The lives of her friends, family, and former sworn enemy or the power of the four Alicorn Princesses. Her choice.
