I think that the Combine soldiers are not the inter-dimensional aliens themselves, but actually mutated humans augmented with machines. In the Citadel, you witness some of these mutant humans working on a machine next to a Combine soldier. Maybe Nova Prospekt is some kind of recruiting center for the Combine?
This could mean the real Combine aliens are the dropships, gunships, and striders. The Combine "leader" is seen talking to Dr.Breen a couple of times in the game and it does not have a humanoid face.
Maybe the Combine were going to assimilate every human and use them as soldiers in other dimensions?
