You know what...yeah. I think it works. It's a bit of a stretch, but shares sounds with

Francis Finn would also make a great combo.
Question though, if you've loved
Francis for years, why wouldn't it feel natural to call a child
Francis?
On another note, it might just be me, but I find your text color difficult to read.
