A Swarovski Z3 3-10x42 requires medium Talley's for the bolt handle to clear the ocular. Objective clearance is not an issue and the mounting height was reasonable with the 42mm objective. Compare the Swaro dimensions to your Kahles and you will have your answer on fit.
Personally, I would get a bigger scope to make use of the dead space you'll have between the barrel and objective using a 36mm objective. Switching a tactical style Scout bolt handle might help reduce height if you don't want to use a bigger scope. The 'knuckle' on the butter-knife style handle is what creates the need for more height.
