Yes, he can. His friends will become subscribers to the new page.

When you convert your personal account to a Facebook Page, we'll transfer your current profile picture and add all your friends and subscribers as people who like your Page. Your account's username will become the username for your Page, and the name associated with your personal account will become your Page's name. If you want your Page to have a different name, consider creating a new one.

No other content will be carried over to your new Page, so be sure to save any important content before beginning the conversion:

1. Download your timeline information. You can download a file that contains all of your sent and received messages and all of the photos and videos you’ve uploaded to Facebook.

2. Appoint a new group admin to any groups you manage. You'll be unable to manage groups once the conversion begins.

When you're ready, start converting your personal account to a Facebook Page.

Once you are blocked on Facebook you are blocked from seeing that person's profile and anything about that person while you are logged into the account that is blocked.

However, if you create a second account or have a second account to log into then you can see that person's profile with the second account that is not blocked. As far as the full profile you would have to more than likely become friends with that person depending on the privacy settings that person has set for his/her account.
