I highly doubt that. While it's possible, I doubt either pilot group would give up SLI rights to just do straight DOH, because well, it's stupid to do that. Many mergers have transpired where different formulas were used to calculate seniority position. Career expectations (time to upgrade) plays a large role in Seniority List Integrations. ALPA has entire seminars on SLI and mergers. Have you been to any formal Mergers Training? I have.
