While it seems a good idea to create an aggregator site and help readers to read from one source itself, it is not considered appropriate even for non-monetization purpose and the site will start getting notice from original content resources pretty fast. Two real life examples I know :
In 2007, I started a website on US Presidents and started scrapping the Presidential Election News from various websites using a WordPress plugin (Now deprecated). As it was a pre-election year, so many articles were being written on the subject and soon my site started getting traffic from search engines despite having duplicated content. However, the site remained successful only for 2 weeks as I received dozens of warning emails from editorial staff of media houses whose articles were being scapped by my plugin. While, some people appreciated my efforts to create a single source for all Presidential news, they politely asked me to at least remove the articles owned by them. I had to shut the site finally.
Second example is of a website in India which started an aggregation of daily Editorials published in Newspapers in India. The website had a new idea that quickly became popular among readers preparing for government job exams. It provides high-quality content on current affairs issues. However, one day the website went offline, never to be revived again.
So, the chances of any success in this field are very slim. Proceed cautiously.
