WoB: can enough Stormlight allow a Heightening level up?

[Reckless Disregard]

Anyone have a WoB on whether someone can level up on their Heightenings with Stormlight? Or do they need (can only use) breaths to level up?

Yes, Stormlight and Breaths can be used interchangeably. But is there anything on whether you can have a sufficient amount of Stormlight to create a heightening jump. 

If yes, did Peter work out the math for this? If you need 200 breaths to get the the second heightening, how much Stormlight would you need?

thanks!

Because stormlight doesn't grant the same effects as Breaths, the only way to do this would be a hack

I assume you can't do It.

The Stormlight is Kinetic Investiture (mostly Fuel) alone.

The Breath is this funky stuff that sometime acts like Kinetic Investiture and sometime as Innate Investiture (stable Investiture that Composes Souls for example, or Spren).

You have also to consider that if It was possible,  Stormlight leaks away, more Stormlight you hold and bigger the leaking becomes...I assume you can't stack enough Stormlight into a man to reach the equivalent to Heightenings (also the lower ones).

This if It's possible, comes easier with other magics...but I assume Stormlight isn't a pratical way
