I nominate Ben Barnes to play Curufin, the son of Fëanor most like his father. Barnes looks quite a lot like Richard Armitage, who plays Fëanor, and is well suited to play one of the least likeable of the Noldor.
I know he don´t look too much like a young Richard armitage at first sight, but look at his mad stares... he´s really good at that, and i can definitely see him as a hot-headed, hot-blooded trouble-maker, like a younger Feanor...
Let's make things interesting. I nominate Aidan Turner. Yeah, rumour has it that he was miscast as a Dwarf, but let's avoid thinking about that and admit that he would be perfect as this scheming, haughty, fiery Fëanorean prince. https://www.imdb.com/name/nm2636108/?ref_=nv_sr_1
