If I were starting a 5E Eberron campaign today, I would implement dragonmarks as magic items, a la 4E alternative rewards. A least dragonmark could be comparable to an inherent wand of some cantrip (or boost the efficacy of some cantrip). A greater dragonmark would be something that would fill an attunement slot, more on the level of a rare staff. Obviously, this approach requires greater trust between player and DM, so I'm not sure it would fly for a published campaign setting.
