Using your neighbor's blood slaves on the battlefield

[tinkthank]

I havent played Abyssia using blood magic much because I have never liked giving mages slaves, since they never Last long without becoming toasted crispy bacon bits.

But was wondering: unlike gems, which stay in your pocket during a battle, slaves pop up and hang out getting fried on the field, so do you think it would be possible to use someone else's slaves? By this I mean: have a friendly commander who doesnt happen to radiate deadly heat carry around the slaves, they pop out and hang out around him (a few squares away) and your mages can use them. Would this / could this work? (Note that Abysia has no natural non-toasting commanders, so you would go have to find some.)
