I for one would not go by names, and their accomplishments, deeds, and etc. Sure, there's symbolism in picking those who deserve it as such, but you can send a great message in this person - not based on deeds but based on his height.
I would put a call out for the shortest of gnomes to come forward, who will be the first holder of said torch.
First, due to his size the torch itself will be his same size...maybe even bigger! It would take great strength then to hold this torch, much less carry it. He'll do it though - may tinker up some gizmo that has wheels on it so he can push it along a little while carrying it. If you ask me, his strength in carrying an item as big as himself shows greater strength than any other individual could display.
Don't even get me started on the stairs. Those will be a pain.
Then when he gets to the brazier, he surely can't reach it you know. And you can't just toss it up in the air and HOPE it lands in there, oh no. He'll have other gnomes hoist him up till he can reach it. This shows unity and cooperation - once again something nobody else can show. If you ask me we don't see much of that, and we all know the straw is stronger when in groups.
And then once the games start, we can all sit back and enjoy Gnome-tossing, which mind you is a guilty pleasure we all secretly enjoy. Even gnomes like it, taking flight is one of their fancies - they just don't appreciate the landings.
