As Mediafrog notes, the plan is to upgrade the 92.1 translator to 250 watts from its almost Part 15 status right now. At that point, it will cover the Tarrant County side of the Mid-Cities reasonably well, though I understand KTFW is, or was, fighting it. Whatever is done with that translator, it will have to relay 1630. I'm thinking that's one that will have to be paired with that translator for life as I'm pretty sure Mortenson got it free in the AM translator window.
I last lived in DFW almost 25 years ago, but the old KCLE-FM 92.1 came in quite well where I lived (Hulen and Vickery area). I worked in Arlington in what's now the Chase Bank building about a block north of Park Row and Bowen, and I remember being able to hear it there, too. I tend to think KTFW will have cause to be upset if that translator signs on, though it will depend on how many listeners complain of interference.
