The flood, unlike a Half life creature, do not take over a host organisim and adapt it to its own.
The flood are a race, as you can see in Halo 1 they never, pardon my french, screw a dead covie to turn into something of a melange. The Flood are a species, they feed on living biomatter, more appropriately, anything that's got blood. They spawn and reproduce in an asymbiotic way. Therefore, I highly doubt you will see any cross breeds between covenant and flood.
