I wouldn't change your ratios. Upping your carbs isn't a great idea IMO. I would recommend just eating more. Eat three eggs right before you go to bed every day so keep your body processing protein while you sleep. Also, start deadlifting and doing squats. Start packing away more calories in the same ratio. That way, you'll gain lots of lean muscle without accumulating too much adipose tissue. Upping your carbs will just cause you to gain body fat. The goal here should be to gain weight by adding lean muscle mass, not just gaining weight for the sake of gaining weight. If that's the goal, you'll almost always gain unhealthy weight. Adding healthy weight takes more time and work.
Don't put your trust in anyone on this forum, including me. You are the key to your own success.
