If the webtoon "Castle" were adapted into a drama, wouldn't Yoo Hae-jin be the best fit for Choi Min-wook?

I feel like Kim Shin's image and action style would be similar to Koo Do-hwan. Due to the nature of the webtoon, there are many multinational roles including Russian and Chinese characters, so casting might be difficult, but I really hope it gets released as an OTT series.
