If I were to add an Alliance race extending from WC2/3 as an alternate TBC thing, then:
Wildhammer Dwarves - Taller, wilder versions of Dwarf. Plenty of outdoor racials
High Elves - Really no reason why we're discounting them. At all. If not High Elves directly, then we can make due with Half Elves, as was originally planned in WC3 (Ranger hero was Half-Elven)
Dragons/Dragonsworn - Plenty of Alliance connections like Krasus having been part of the Kirin Tor and plenty of Blue's being present in the Manga stories, which were set around WC3 timeline. Even a Dragonsworn or Dragon-descendant race could work.
Golems - Not exactly lore based, but they'd easily as a total reinvention of a race, much like how Draenei were reinvented. If we don't have Gnomes, then have em be replaced with a sentient Tech-savvy race of Golems with new origins. Something that looks like the Iron Watchers from Storm Peaks, but much more heroic. Tie em in with Dwarf/Titan connections. They could be an interesting dynamic to some of the larger Horde races, and something to fill the archetype of the large Draenei. Have them bring in Crystal-based tech, have them have connections to the Titans, have them be adept in Engineering and mechanics.
