On the Space Wolves, no, but Salamanders should be alowed to have successors. Also, about the empires, the Imperium does not rule the galaxy, there are huge patches of over 2000 worlds which were never part of the IoM, not to forget halo stars and the now, ever fading reach of the Astronomican.

On the Tau Space Marines, maybe those space marines have a mental flaw, you know, Taurans were hyper xenophobic from their founding..... so, if it is a well tought out mental gene-seed issue thingy and several other factors, why not alow it?

On loyal traitors..... hmmm, cmon, we all "know" that Blood Ravens are Thousand Sons, but, there is sadly no canon fact. This is a grey zone..... The logic could go: if these astartes were so loyal that they weren`t currupted during the hardest time of heresy, then we should keep them.... or so
