The KOTOR override package works because it does not overwrite the base content. The game engine will still call the original plt in the game resources. You can replace original heads per Zwerkules (so the answer to your question is yes) but you can not do so unless you compile your changed heads in a hak (so your extended answer is not in the manner you want to replace them).
Builders must use a hak and players must have the hak and use the override together for heads to show correctly during creation and play or else the game will not recognize anything past the standard heads and will call the plt from the original resources with no hak present.
Edit: As an aside, this is also why head packs that have heads numbering sequentially into the 49-100 range need to be copied from the hak to the override, as there are a number of helms that exist as head models (from the standard resources) in that range that will have their plts appear in place of the any similarly numbered head plts during character generation with an empty override.
