Well Mr Musk, it is your R&D, the booster, if i'm not wrong.

 

I think you can dedicate a portion of the wing for the fuel,

for this to work. But if it will be strong enough,

or if it needs more rockets dedicated to the cause. No idea.

 

I also don't know if we are talking about this particular thing. XD
