Although Xie Wen knew that asking this question might make it harder to obtain the Poneglyphs in Big Mom's possession, he still couldn't suppress his curiosity...
It seemed that after spending so long with the cats, he had picked up a bit of their nature himself.
Since he had already given her the idea, Xie Wen continued, "Even if they don't know what the writing on them means, the Poneglyphs themselves are so tough that they ought to be pretty powerful after becoming Homies, right?"
As for other people seeing them once they became Homies and ran around...
She could simply leave the Road Poneglyphs unchanged. The other Poneglyphs held no appeal for most people. The only concern was the World Government coming to cause trouble, but would Charlotte Linlin, one of the Four Emperors, worry about that?
Besides, she could always put some clothes on the Poneglyph Homies or something. There were plenty of solutions.
"Hm? You're right!" After a moment of stunned silence, Big Mom suddenly clapped her hands and burst out laughing. "Mamamama! You're so clever! None of my children or subordinates ever thought of that! I'll go try it right now!"
As she spoke, she got up from the floor and hurried toward the place where she kept the Poneglyphs.
Xie Wen shrugged, then continued leading the others out of the Castle.
Although he was curious about how it would turn out, he doubted Big Mom would let him watch.
Still, with Shalmeow's Observation Haki, perhaps she could work out roughly what happened from the "voices" she sensed... and confirm where Big Mom kept the Poneglyphs while she was at it.
Not long after they left the Castle...
"Xie Wen, sweetie~ It looks like she failed, meow~" Shalmeow, who had been resting with her eyes closed
