It should definitely help. To account for the change in the start date when deadline is being measured, consider a short deadline of about 3-4 days. The deadline starts to increase update process priority as it gets closer, so the first couple of days are still in the "as non intrusive as possible" mode for your users. Most update healthy devices will complete the install and even restart outside active hours in that timeframe. Then, use the Grace Period to really define how long you want end users to have controls over when to restart along with restarting after active hours... to have a low-impact restart. Once both the Grace and Deadline expire, the device restart will be enforced to ensure your patch adoption and security needs are met. HTH!
