I have not come across any fluff on the Lions apart from the Grimaldus Story, there are, according to the lexicanum, only 3 sources of information on them.

Alas as for the inquisition and the mechanicum (which controls the gene seed tithes), go through, will deal with taint.

If we look at individuals like the non canonic Ultramarines game, where Titus is taken in by the Inquisition) or simply the Abyssal Crusade, where 30 chapoters were suspected of taint and hence sent to their doom...

We can look at many chapters that have been declared excumminicatre traitoris just an excerpt:

Sons of Gideon --> gene-seed mutation

Knights of Blood

soul drinkers

damned company of lord caustos--> circumstantial evidence

adhgaron's reavers (former sons of guilliman company if I am not mistaken) the list goes on and on with many traitors and tainted people ;)
