Restore Unused Peds is a San Andreas mod that restores cut, removed and unused peds from the game, there are a lot of mods that do this, but this one is the most complete and stable of them for more info, go to the original author of the mod. This is an unofficial update for me because there are a few things I didn't like about the mod.
List of changes:
Restored MEDIATR, original model;
Restored HECK1 and HECK2, original models;
Restored BMYCON, black varital of WMYCON, original model and voice;
Restored TRIADC, original model, now the triads will have 4 members instead of 3;
Restored the triad unused voice banks, now they will have more voice variety;
Removed BLUE2 and BLUE3, as they don't fit into the game.
