Increasing the level cap but reducing available experience

Out of curiosity what do fellow adventurers think about increasing the level cap of BG EE however reducing the experience given throughout the game for killing creatures or completing a quest (for arguments sake let us say a reduction of 10%).

This is not a feature request and not necessarily something I would support but rather I am just trying to look at the game from different points of view.

Thoughts and opinions welcome as always.
