Creative nn's for Leopold?

I like [name_m]Leopold[/name_m], and I love nicknames but [name_m]Leo[/name_m] is just a little too popular for me.
Does anyone have any ideas?
I kinda like [name_m]Polo[/name_m] but one of my fave girls names is [name_f]Persephone[/name_f] nn [name_f]Posy[/name_f] and I’m not sure [name_m]Polo[/name_m] and [name_f]Posy[/name_f] sound too good together…

[name_m]Polo[/name_m] was my only thought!

[name_m]How[/name_m] about just “[name_u]Po[/name_u]”?

What about Leap/Leep?

[name_u]Lee[/name_u]
Leopard
[name_u]Po[/name_u]

These may be a stretch but…

Led
[name_m]Eddie[/name_m]
[name_f]Lollie[/name_f] (cute but sort of feminine)
[name_m]Lenny[/name_m] (with an ‘n’ middle name)
[name_m]Lem[/name_m] (with an ‘m’ middle name)

Maybe Opie?
