This picture is great, and really looks like the next generation Wolverine.
He needs to be young (under 30), short, stocky, sexy and with a variation of the classic comic costume like in that picture.
They could go for a current trendy 'undercut' hairstyle, like guys have with cropped beards, shaved sides and slicked quiffs. That would look great.
Something like this or this or this or this
Sounds like Gambit, definitely not Wolverine.
Wolverine always looked about 50.
We don't need recast, and we don't need Wolverine in movies now.
After total reboot of serie, not at this moment.
