Ericles

Really fun catch, but I'm almost positive this was just done by lashing, which would be just as incomprehensible to Adolin as awakening.  My guess would be Brandon just teasing, otherwise I think there would be some really obscure easy to miss reference about color draining from another object, and I haven't seen it.

Although...he does wear all white (or gray at one point?) yeah....i still think were just reaching here.

Who knows with the Cosmere though.

I also wondered about the names and their similarities.

However, as Vasher has been revealed as Kalad and Peacegiver, and Ive also read that Vasher is Zahel in WoR then I doubt Kalad/Vasher/Zahel can very well train himself (Kaladin) in swords (baring fun temporal paradoxes....which I wound put past our Mr Sanderson)

I just finished Warbreaker. If anyone has any other crossovers to point out, id love to hear about them (i know about Hoid and Nightblood)
