The only unsigned mid to high level D-I senior prospect that I know about in DFW is Lincoln’s Gary Flowers. There was interest from SMU in Flowers but apparently grades will force him to go the JC route.
This year’s junior class is loaded. Leading the way is Q’s cousin, Darrell Arthur. He’s regarded as the best player in Texas and one of the ten best players in the country.
Mike Kunstadt's Texas Hoops usually has a pretty handle on the top players in the state. Here's his list of the state's top junior prospects:

As for the DISD schools you mentioned, here are their D-I prospects-
SOC:
Darrell Arthur - jr.
Kevin Rodgers - sr. (Baylor)
Jerel Hastings - sr.
Kimball:
George Odufuwa - jr.
TJ Clark - jr.
Lionel Booker - jr.
Lincoln:
Byron Eaton - sr. (OKie St)
Gary Flowers sr.
Derrick Moore - sr. (SW Miss st)
Rich Jones - so.
Seagoville:
Ryan Boyd - sr. (SW Miss St.)
Donald Sloan - jr.
Derrick Rowland - jr.
BTW, a guy I really like and I've seen play several times is Ugo Chinasa of Richardson Berkner. He's about 6'8" and very long. I think he's a great prospect with a huge upside. He's a nice football prospect as well.
