Cryhavoc, its not as bad as you make it sound.

if you take a really inbred super enchi and breed it to a really inbred super fire, as long as the super enchi has different ancestors than the super fire, the offspring will not be inbred.

there are calculators that can be used to calculate an inbreeding coefficient for an individual based on all available knowledge about the ancestry. and with the right pairing, its possible to reset it back to zero.

if you go far enough back in time, every individual is related to every other individual. its even true for humans. for example, more than 30 million US citizen are related to the 102 pilgrims that arrived on the mayflower, and the majority of chinese people have Gengis Khan in their ancestry. also, most people of european descent have the ability to digest lactose, people of other origin can digest lactose as children but lose that ability in adulthood. this traces back to a single mutation that happened in a single person around 6000 years ago somewhere in central europe. so if you can tolerate fresh milk, congratulations, we are related. in iceland there is a popular smartphone app, if you enter two icelandic people, it performs a database search based on records that go back centuries, and in most cases it will find the name of the last common ancestor.
