Why not get a hair transplant for the front hairline (with a reputable surgeon ofc), leaving the crown area to go bald naturally but use a hair-system to cover that. I figure that combo would be less noticable than a whole hair-system.
In theory, this works. I have done a few of these and found that all the men went back to their hair systems, which pulled out the hair transplants. They never waited out the results. If you want to transplant the frontal area and then use a hair system behind it, that makes sense, but the burden is on you to follow through properly. I have been doing hair transplants for 33 years, so I have much experience to share.
