Always had a problem with companies that thought they knew better than the manufacturer. Boeing checklists only have critical items (not necessarily your company checklist; even if you are told it is "Boeing" it is probably not) and the Before Takeoff Checklist should only have Flaps. The control checks, doors etc are now part of the Before Start checks or After Start. Flaps has no part of the pre-taxy procedure because it sometimes has to be set just before takeoff. Setting flaps while on the ramp also reduces ground clearance, presenting a chance of damage due to collision with ground equipment, and in addition reduces the ground observer's vision when checking for pushback obstacles.
So supposing you use the correct (manufacturer's) procedures, simply carry out the Pre-Takeoff Checklist before takeoff. Simple. End of story. If you don't, still carry out the Pre-Takeoff Checklist before takeoff. What is hard about that?
