well the great part is that the HT head is a bald sculpt just like this one. The only issue I can see is the fine little sliver of hair that is remaining on the top bangs on the SS Luke sculpt. It might require a little meatball surgery to do a little "Hairclub for Men" action on it so the bangs are there for the sculpt. If that is something of interest.
Yeah, seeing is believing for me, but thankfully I know that'll happen sooner than later with Tatooine Luke being released so early -- my tentative plan is to buy two of those, with one version to part out (there are so many accessories that making most of my $ back shouldn't be an issue). I also have the sweaty Stormtrooper Luke coming and maybe he'll be fine on the Tatooine body.
I do like that SS thought to include the bangs under the helmet, possible those will work well enough--the top of the head might need some padding since Tatooine Luke will probably be lopped off up there.
