This doesn't really work as far as I can tell, RAW or RAI. While it is the case that in theory a Melee Attack with a Heavy Ranged Weapon would satisfy both criteria, there is no weapon that can normally perform such an attack, as far as I'm aware. Using a Heavy Crossbow or a Longbow to make a Melee Attack would be attacking with an Improvised Melee Weapon, which is both not a Ranged Weapon and does not have the Heavy property, so neither Feat would be useful.

If we are being generous we could say that attacking with a Heavy Crossbow would be like a Club and a Longbow would be like a Staff, and per the Improvised Weapons rules we could use those weapon stats for our Improvised Weapon, however, note that neither of these have the Heavy property, so you would be unable to use either Feat in this case as well. (The Heavy property, particularly on Ranged Weapons, seems to be not about the weight of the weapon (an intrinsic property of the thing), but about the strength required to attack with such a weapon in it's intended manner. In this way it would make sense that neither Feat would work.)
