Oh, the system can handle it juat fine, but with headaches the designers decided early on they don't want to deal with, unfortunately. Karl David Brown, who used to post here, has reverse engineered the system WitC uses to design Species, and has actually put out perfectly viable and balanced Large options and how to use them:
"The half-ogre was one of the first optional races for D&D, first described in print by Gary Gygax himself!"
"Ogres and half-ogres of the worlds of D&D are diverse and sometimes surprisingly civilized. This booklet provides five new player character race options: the ogre-blood, half ogre, ogrillion, wild ogre, and civil ogre. All these races are designed for balance with a proven mathematical system and play tested by a 30+ year veteran DM. Each is given a full write up like the races in the Player’s Handbook. These write-ups draw on lore from the entire history of D&D."
"Also in this book are ogre Flaws and Bonds, a selection of Large sized equipment, a new feat for ogres, rules for Large player characters, design notes, the history of ogre and half-ogre races in D&D, and stats for gigantic pelicans!"

His overall breakdown of the system underlying Species options is fascinating, and has had tremendous predictive power since he first started putting it out like 6/7 years ago:
