I'll be the first to admit my priorities and views have changed with age. When I was young, like 2/3 to 3/4 of motorcycle dealer employees tend to be, I thought having all this crap on a bike was stupidity, sacrilege, and admission that someone wouldn't and couldn't ride very fast or skillfully. I couldn't stand heavy bikes of any kind (heavy was anything over 400lb.), and anything with any non-performance or non-ergo options on it was a insult to motorcycling purism.
It's nothing short of amazing what 20 years has done for my perspective! I'm older, and I like to be comfortable. I enjoy my creature comforts, but on a bike that can still handle, has gobs of power and can go fast.
The younger staff at the dealers I usually frequent don't care much about anything but the Panagales, Monster 1200s, the RnineTs, the S1000RR, S1000R, and the most concessions they're willing to make toward even light touring are bags on the S1000XR or R1250RS.
If it makes me happy, I don't care. I thought a lot like them until I got well past 30, so I wouldn't take any offense, either, OP.
But I do love catching them talking, so I'd never let on I had seen or heard anything, and would do what you had in mind and then give yourself a good laugh at what they said the next time. Come up with a couple of BS contraptions, give them a backstory and see if they buy the BS with any of it. You have some time to think about it and plan it out.
