I used a pump for 10 years and now do shots (Type 1 for 37 years), so a dual wave bolus makes sense, although I would not go to bed for at least a few hours after the bolus to make sure you don't go either severely hyper or worse, severely hypo. A dual wave might smooth out a high - if you do go high, you'll become more insulin resistant and therefore need additional insulin. For me shots work a lot more predictably - a steel tube vs plastic cannula just works faster and more reliably. So you could try injecting the bolus even if using a pump, then use the pump for additional slow release bolus.
And as an alternative you could spiralize zucchini into noodles and add a tasty low carb sauce (most sauces here in the US add sugar). I've found this to be a good low-carb pasta fake, and you'd need a lot less insulin.
