I dont think Yhwach has powers comparable to the Soul King bcz Yhwach is a 1000 yr old quincy while the Soul King has probably been around since the beginning of SS so its hardly believable.

Also at some point the Gotei 13 most probably ask Aizen in winning the war due to his fusion with the Hogyoku. Ichigo understands Aizen and might be able to work together though the partnership possibly be brief
