Loma vs Pacman won't happen IMO because Loma is fighting 3 2 division south of 147lbs which Manny is campaigning and this time in their career i think catch weight is not advisable.
Loma vs Davis or Loma vs Garcia would be explosive but Loma needs to focus first on Lopez and not take him for granted. In boxing, it would be stupid to think that you are going to an easy fight as there's no such thing as an easy fight.
I also want a Loma Garcia to happen, they are today's generation biggest attraction and we all want to see the best fighting the best, I hope promoters will not deprive boxing fans of great match up like a Loma Garcia match, sometimes promoters and managers the one preventing great fights to happen like the case of Wilder Joshua fight.
