Using magic systems from other worlds

[NobleD he/him]

I was at the B&N Calamity signing and asked Brandon a question related to using magic systems on other worlds.  I know that some of this is information already known, like I knew that Vasher was staying on Roshar because it's easier to get stormlight than breath.  But what I wanted to know was could you use stormlight to directly fuel awakening while on Roshar.  Here is the audio, and here is the transcript:

 

 

Me:  I've seen that you have mentioned that it is technically possible to be able to use one magic system on another planet.

 

Brandon:  Yes.

 

Me:  Is it possible to fuel that, like say could you fuel awakening using stormlight, or do you have to bring breaths?

 

Brandon:  Yes, you could.  Excellent question.  Now there are tricks to making it happen on each world.  Some are easier than others, but yes you can.

 

Me:  So could that allow a loophole to allow to maybe convert from one form of power to another, like from stormlight to breath?

 

Brandon:  Yes, infact that's part of why Vasher is on Roshar because it's a lot easier to get stormlight than breath.

 

 

I had wondered if it was possible for someone to say go from Nalthis to Roshar, use stormlight to awaken something, then travel back to Nalthis and gain a bunch of breath from the item awoken with stormlight.  It sounds like it may be possible, though very difficult and would require knowledge that few people have.

[Stormgate he/him]

I would say that it is possible, but would require some serious hacking of magic.

[Quicksteel he/him]

Seems like it would probably be pretty difficult to accomplish but probably worth the trouble since breath is fairly hard to come by.

[Straw he/him]

I think it would be possible and not too hard too do considering that both are investure in its purest form aka gas form.
