If you're going to give a custom diet then you do need to have a better idea of the nutrients you will be giving in addition to the pellets.
Pellets are far from ideal as they don't offer any opportunity for feeding naturally (foraging, opening seeds etc) & the ingredients aren't always the best.
I'm not sure your plan to give just a few pellets a day is going to allow her to create an adequate hoard, you do need to feed enough to allow for that.
Hamsters need to have an adequate amount of food available at all times so it's best to fill the bowl or scatter enough for a few days at a time.
The protein in the pellets is on the high side already so you wouldn't need to be adding in extra protein foods, if those foods were to replace pellets then you would also need to know the other nutrient levels in them.
Pasta as a treat now & then is fine if they enjoy it but unless it's wholemeal pasta it won't offer much in the way of extra fibre.
It does sound as though you want to give your ham a healthy varied diet but tbh I think you would do far better to give a good muesli type mix like Hazel Hamster which has good ingredients & allows natural feeding behaviour.
You could give a wide variety of fresh veg in addition to that, beginning gradually & working up to a small piece daily.
Once or twice a week a small piece of nut or other seeds can be giving in addition too but I would stick to a good quality mix as the base of your hamsters diet.
