Ralf and Michael raced together in F1 in the 90s and 2000s, and now 17-year-old David - a Formula 4 rookie of the year in 2018 - is preparing to move into F3.
Kolner Express newspaper says David is testing a F3 car at Sepang this week.
When asked what it would be like to see two Schumacher's competing again in F1, former Williams and Toyota driver Ralf said: "That would be a wonderful dream.
"If if comes true for both of them, it would be incredible, mega," the 43-year-old told the German broadcaster RTL.
However, Ralf admitted that it is far from a certainty.
"We all know there are not enough places in F1, and the closer you get to it, the thinner the air," he said.
