Assign Feature Pack to Site Subscription Using Server Object Model

Hello Experts,

I have created a site subscription using server object model with Sharepoint 2013 foundation. I did same thing with Share Point management shell. But now I wanted to do it with Sharepoint server object model.

So Now I am stuck with a question. How can I create and assign feature pack to the Site subscription from the server object model(Not from share point management shell-Power Shell). I have followed this link to create site subscription with sharepoint server object model.

Is it possible to create feature pack and assign to Site Subscription with server object model.

Please let me know your comments.

Thanks in Advance. :)
