Re-writing Galad Damodred to fit the Silm is fun (and not just because of the whole World’s Most Beautiful Man):

When he thought no one could hear him, Gadwar’s father would complain how he missed his chance to cross aboard the stolen Swan-ships, and had that not happened, he and his family would not have had to cross the ice desert. Had he boarded the ships, his first wife would not have had the opportunity to decide to disappear into the darkness to die of despair somewhere in the fathomless cold. Gadwar’s older brother had been even younger than Princess Idril during the crossing and had little memory of his mother. When Heledir, Bân, and other veterans of the Helecaraxë spoke of the endless darkness and cold and of everyone who died during the crossing, Galuven could only offer vague memories of a freezing nose. Thus, Galuven lacked the resentment that plagued their father. Tarlangon had been an opportunist searching for power, latching first to Fëanor’s reactionary party, then switching to Fingolfin because of the far greater number of followers. Any words that would grant him more status at court and more public attention to his studies and publications Gadwar’s father said, with whatever pronunciation he needed to. Tarlangon did not possess the single-minded devotion and loyalty demanded of those allowed to board the stolen Swan-ships.

Anyways, there was no opportunity for him to rejoin the following of Fëanor’s sons once he remarried.

Gadwar’s father married his mother, a noble woman of the Mithrim Sindar, for political stability and power – and to have someone to care for his young son. How much his father loved his mother, Gadwar could not guess, and his mother spoke of Tarlangon in only a fond but distant neutrality. Meluiniel’s own motives for marriage had been equally calculated, she once admitted in private, as a young Gadwar once again listened from corners that he was not meant to. She had no strong desire to be a wife, but she strongly wished to be a mother.

Galuven treated Meluiniel as if she were his birth-mother. He had little memory of his first mother and little reason to cling to her memory. Meluiniel taught him to read and write, to ride a horse, to account his finances, to sing and dance, and to comport himself as a righteous man. The last was a particular sticking point to Gadwar, for if he were to describe his older half-brother with a single phrase, it was that Galuven was concerned that his every action be morally just. Perhaps it was fortuitous that Tanlangen died a year after Gadwar and his twin sister were born, for Galuven disapproved strongly of his status as Exile.
