Capillary Tubes. Is length a critical design factor?

I have been trying to find out how much the length of the capillary tubes, in my domestic dual evap fridge circuits is a critical design factor. How much can be safely cut away without causing too much control discrepancy? There are two small coils of 2mm OD cap tube behind the fridge, can an inch or so loss, be OK?

Second question: If one of those cap tubes is plugged, like really plugged, do you think I could mod the fridge by drilling a small hole, at the site of the cap tube coming out of the wall, inside the fridge/freezer box, right through to the back of the fridge. Take an educated guess at how much cap tube is running through the wall/foam core add that to what is coiled up behind the fridge, and replace the cap tube with a new one?
