I agree that Vex allies are not lore-friendly, but Fallen and Cabal would actually work. This is because they do not serve the Darkness at all. You are looking at this the wrong way. You're trying to come up with a reason where Cyrus forced the House of Scars and the Scorch Hunters to join the Frontier. The real reason should originate in that both the Fallen and the Cabal joined of free will. My idea is that Beriks and his surviving fragment of the Scars joined up with the Frontier because they realise that the conflict between the Guardians and the Eliksni is pointless, and all the death caused by it is unnessecary. Thus, they join to put an end to the potential slaughter of the Eliksni. They also want to correct what was made wrong, and possibly make it so that both races can live together in peace.

Va'akirn and his Burning Legion fragments joined because they want revenge on Reu'ulan, who dishonorably usurped the control of the Legion in a simple attempt for more glory. They also see that Reu'ulan could potentially doom all of the Legions in the solar system, since he would concentrate on crushing the City and the Guardians, while the real reason why the Cabal actually are here and fighting is that they were supposed to fight the Hive and Vex, which means the forces of Darkness. Reu'ulan's actions would mean that even if they were victorious, the victory would cost the Cabal a ton of soldiers, but more importantly, even if Reu'ulan would see it as a victory, it wouldn't be a real victory for the Cabal. Unless they have accomplished their mission, Cabal forces cannot return to their Empire. This would mean that severely weakened, the Cabal would still have to continue fighting. So Va'akirn wants to stop Reu'ulan from essentially dooming the Cabal in our solar system.

I hope this is enough to show that we can keep the Fallen and Cabal as allies. I can give you more to show this, but I hope this will do.
