The stolen shield and severed head are sufficiently ambiguous in scale that he'd work fine in 28mm too - perhaps in the 'minotaur class' (guardian beasts?) in Kings of War.
I also plan to combine him with smaller beastmen as a 'unit filler', perhaps as the central third of a 120mm-frontage unit in Impetus or as the command company in a Fantastic Battles group.
These are terrific 15mm bugbears sold by CP Models. Although originally designed by Bob Olley as 15/18mm, they're marketed as 20mm, but to my eye, they're a bit short to be 7'+ in that scale (though they would make great hobgoblins. They would also make terrific 28mm goblins (of an especially fierce and hirsute sort).
I'm going to base these together on a 40mm square, so that they can be used as brutes (doubled warband) or behemoths in Hordes of the Things or as some sort of super-heavy infantry in Fantastic Battles. As I have at least three more bases to do, they'll be able to double up to give 80mm frontages for Impetus or work as goblin 'luggits' in Kings of War with a couple of individuals on 20mm squares between two 40mm bases (thus giving a 100 x 40 footprint). And for Hobgoblin, I'll just throw a few bases together to make a unit.
I've been trying out this simple yellow skintone on a lot of 25mm goblins for D&D. I'm quite happy with it - despite being such a bright colour, it's somewhat subterranean-looking, somehow, and it just squeezes into Tolkien's 'sallow' bracket for orcs.
(Below is a scale comparison with 1/72 Dark Alliance orcs and "15mm" Battle Valor orcs - base still to be painted and matt varnish still to be applied!)
