Multiple Blogs to One Blog

I have not used the plugin yet and am new to syndicating blogs, but I was wondering if I could use this to pull in blog posts from a variety of niche blogs into one main blog (my lifestyle blog, showing all of my niches).

I have been wanting to do this for a while because there are people that, for example, are only interested in what I publish about filmmaking on my filmmaking blog and wouldn’t care about my photography, but my main site would have both because when people search for my name for camera related work, it is good to have both niches showing many articles.

The link I have added in this post is my main site which only has one of my niches, but many people have told me that lifestyle blogging would be good match for me, since I do a lot more than directing.

Thank you.
