Well, most writers write fresh content this way, except for the spinner chief part. Instead of just copying whatever comes up on the first 5 spots, you could curate the best writeups on your topic, put it together and try to improve whatever is already there on the internet. Once your new post is live, go email everyone who has linked out to the sources you used and tell them you have a better one just published. You may get some solid links this way.

I've ranked websites in the past with spun content, and now they are still on #1 position of google. First year (2014) google found me because my spun was really bad, many paragraphs were just copied and my position drop from #2 to around #20 after a panda update. Later I cleaned all my text with better spun (I didn't buy any article!), my ranking went up again, and with more backlinks I reached #1 and it is still there
