Salamanders are a big no-no. They did not take part in any founding and as such have no successors. Not even implied ones. Chapters associating themselves with their gene seed will only really come off as over-ambitious liars.

All in all this kind of cocktail of gene seeds could cause a whole number of issues. Namely, it's rather overpowered. On top of this, where are you thinking of going with this concept? Does it exist merely for the fact that it's a cool idea? If so, well, we have a new addition to the grand majority of other articles on this wiki. Cool ideas with nowhere to go...

It's also expensive to keep track of. In the field of battle you will have to collect these gene seeds from dead marines, making sure the right ones are taken. It becomes a collector's hunt rather than a case of salvaging as many as possible.

Plus, it's expensive. Chapters should be frugal in their operation. One gene seed is efficient. With one seed, every marine in the chapter will experience the expected mutations and side effects of every gene, the training of new marines and injection of gene seeds is simple and are not open to six or seven different paths of likelihood for errors to occur.

Furthermore, with such a division in a chapter, expect quarrelling. Few chapters have perfect morale records. With every man in the chapter looking and acting like their one primarch, and being certain that his blood runs through their veins, they can all associate themselves as one single entity. With such a tight pact, few marines ever have the desire to let their blood-brothers down.
