[Lance Uppercut]

surely not ?? you can win titles in two different weight divisons in one fight

definitely, if you are under the prescribed weight. And were not talking alphabet trinkets, which I am sure have a rule against it, were talking about the real world championships/The Ring.

but how can you be seen as the best fighter in the lightheavyweight division for example if youve never foguht past 168 ?

The best fighter isn't always the champion.
