Rather than the heat indicator moving from green, yellow, orange and red, just apply the colors to the colored bar within the guage. For example: as the heat bar starts off green as it rises above 0%, but as the heat passes 25% the bar changes from green to yellow. You could make it fancy with a spectrum change for each percentage, or just simple four-colors.
For critical energy, just have the now-empty gauge flash red or something, and keep the sound effect.
The HUD designer can now re-capture this space, perhaps by making the cool shoot indicators larger?
