Even if Martin did have a child, the Dragonfires wouldn't have been lit because a Septim must be wearing the Amulet of Kings to light them. The reason Mehrunes Dagon was able to get to Tamriel was because the Dragonfires, which act as a barrier to the Daedra, weren't lit because Mankar Camoran possessed it (and wore, because his degree of Daedric power was strong enough for him to wear it [I know Camoran isn't a Daedra, but Dagon granted him power.]). If Martin had been wearing the Amulet, Dagon wouldn't be able to reach Tamriel, because the Fires would be lit. I guess the Fires were lit by Akatosh after the fight with Mehrunes Dagon, because otherwise Tamriel wouldn't last against the following Daedra assaults.
