I like the make the internal connections better if possible idea more. That can only help and not hurt if done right.
Also I would add that tinkering with a product often leads to less interest and value on the resale market if properly disclosed because now the product is not what the original vendor sold, but something some guy decided to experiment with.
Ultimately, the decision to tweak or not is yours. It will be an experiment with unknown results until you try. Is that OK with you?
