You can just see my Lenco switches. I can use them while under way at cruising speed. Thumb wrap the throttle lever and can hit switches with fingers. Pretty much same with jackplate but thumb gets that switch. Blinker switch is a clean option. But I had your idea. Ordered, put that thing on and went. Didn’t even know about blinker switch at that time. Well maybe, that was 13 years ago.
