What about Tofino, on the west coast of Vancouver Island?
Drive to Horseshoe Bay in West Vancouver, then take the ferry to Nanaimo, on Vancouver Island. From Nanaimo, it's about 3.5 hours to Tofino - Bit longer if you stop in Cathedral Grove (trees) and Port Alberni.
Alternately, you could do the Sunshine Coast Circle Tour -

They claim 3-5 days, but as you've already been to Victoria you can cut that piece off an easily do it in your timeline. The Earls Cove to Saltery Bay ferry is one of the most beautiful crossings I've ever done, IMO -
