Redirect sometimes will "help" your blog been penalize by google on page rank and serp. Subdomain is treated as the new "domain" by search engine. It's treated much more like an independent domain in many respects - for example, if urls from both the root domain and a subdomain show up on the same page of search results, they do not cluster together.

So, in term of traffic Im sure the flow will ok but in term of seo..I'm afraid to guarantee the effectiveness.
