Great to hear from you and your journey to get to this point. It sounds like things are ticking along nicely with your training. That 24 week plan has gotten literally hundreds of folks up Denali. Stick with it and you should be fine from a fitness stand point. Be remember to keep honing your technical skills.
You might take some comfort in knowing that world renowned ortho surgeon Dick Steadman who performed 5 knee surgeries on me once told me that the ACL was over rated and that a significant portion of the NFL are playing football with compromised or missing ACLs. Dick would know because he worked on so many pro athletes and gave them back their careers.
Good Luck
