[Warhammer 40K] Can a Space Marine "switch" into another Chapter?

Ugh. My Chapter Master is *SO* unfair. Last week, we were all at the "Enchanted Under the Warp Storm" dance. But when me and my Battle Brothers got there, They engaged in close-quarters combat and tactical deep strikes. But *I* said that we should Use Speeder bikes and Melta-bombs to destroy the support structures of the bridge! 

So like, while I hate it when I cause *Drama*, my Chapter Master is pulling this shit all of the time. If nothing else, can't I at least *serve* in another Chapter?

There is one way, brother.  Become a xeno killing veteran, and apply to join the Deathwatch.  Then you can spend your days murdering Xenos in the most efficient ways possible.  There are few things more satisfying than educating T'au on the finer points of chainsword combat, or cracking open  a tyranid's carapace.
