Can Go Woo-suk make a comeback in the KBO?

‌2023 final year in Korea: WAR 0.66
(2019 career high: WAR 3.49)
Roughly 100 games in US Minor Leagues
Roughly 150 innings
Career ERA in the 5s
Except for a short period before his MLB call-up,
his performance in the US Minor Leagues was also quite poor on average
Given this general situation,
if we assume he plays a full season next year without injury,
what kind of stats do you think he will post?
He has refined his breaking balls in the US,
increased his extension,
and he is not the same Go Woo-suk who struggled in his last year in Korea.
An A-grade closer who returns to his prime levels
and hits a WAR in the 3s
VS
Considering his career high was a whopping 7 years ago
and his performance in the US was mediocre, I'd expect...
A B-grade closer hitting around a WAR of 1.
