Can a Marine Chapter do this?

[inquisitorsog]

I've literally never read anything that says they produce more than two ever, certainly nothing that suggests they produce one every five years and one every ten, and only in the heresy series have I read anything about them being removed while the marine is a alive.

My memory may be faulty, but wasn't it also discussed in legion of the damned?

I'm not sure, I've read far too much since then, and it's obviously not that memorable of a book...

More importantly can they do this?

No, Ultramarines have no rhythm.

True, but they're SOB equivalent female PDF, not Ultramarines....
