I've been down that path with cars and motorcycles in the past and it is rarely cost effective.

I would recommend perhaps considering the used bike upgrade path. With a little patience, you can probably spend 50% more in six months and get a used bike with a sub 20 frame & wheel combo with a full 105, Rival, or maybe even Ultegra grouping including the brakes etc...
