Potential Consequences Of A Major Decision (Contains Potential Spoilers)

Does anyone know if it is still possible to max out your relationship with the faction and companion of the location you didn't choice after the major decision that is made subsequent to recruiting Davrin? I'm kinda worried that with the slowed bond ranks, and the inability to sell the random garbage items we find to the faction will make it rather difficult to rank up that faction. Is it still possible to completely rank up this companion's bond and their faction, or do I need to load an old save and work harder on ranking them up faster before recruiting Davrin?
