Been trying to dream up a flickername for him, just not happening. Sadly, no place for him in this group of special human beings
To be fair, you're saying he can't be called 'Lopes' because it looks to much like Lopez when written down. I think you just need to assume that most folk can read
He's known as just 'Cristian' apparently and drops the Lopez. I heard Flicker shout out 'Cristian' from the touch line as well so I'd go with 'Crissy'.
