Sorry it's taken so long to get a reply to you, Boris, I forget to pop in here when I'm not part of an active roleplay!  
ANYway.  
I think that's an awesome idea!  
Because if I were a god and another god killed my cat, I'd for sure give up my powers to bring back the cat. >>; 
But he'd still have his ability of reasoning and all, so he could easily be a tactician in his planet's war.  
But then comes the question of would his planet's people accept that... 
Hmm... 
So, yeah, sounds like a wonderful idea. :3
