I think this has enough of a grey area that common sense thinking about the skills of shooting and throwing make it clear enough that RAW sharp shooter does not apply to throwing. I've done a lot of each and in my experience swinging a baseball bat (or sword) has a lot more in common with throwing a ball (or knife) than shooting a gun (or crossbow).
Here is how I modified my campaign to allow for the feat:
Perfect Pitch
Honing your skill at throwing weapons you no longer gain disadvantage when throwing a weapon beyond it's normal accurate range. You ignore half and 3/4 cover when using a throwing weapon. Additionally, your superb skill at short distance with a thrown item means that you have better focus on your opponent's better protected or small vitals. Your may throw a weapon suffering a -2 penalty to hit with an increased chance to critical strike (19 or 20) when in what is considered the normal accurate range for a thrown item.
So basically, if a hatchet is 20 ft normal/60 ft. max (disadvantage) range , it is now 20 ft. (+crit), 60 ft max range. It doesn't stack with Champion bonuses and I think is still may be a little OP for thieves so I left out the ability to draw 2 weapons.
Regarding that however, a "Quick Draw" feat will soon make into my game. This allow a player to draw one extra weapon between attacks once per round. This also makes it nice for melee characters should they find their sword does little damage to a skeleton then switching to a mace for their next attack, and for those with multiple magic weapons with recharge rates.
