Can't we rename it to Cheongwagung to make it sound cooler?

The name Cheong Wa Dae feels a bit light and lacks prestige.
Is there a reason we can't change the name to Cheongwagung,
like the presidential palaces in other countries?
Like "Blue Palace" in English.
Is the reason we don't call it a "Palace" to follow the US White House
and just call it a "House"?
The name of the Élysée Palace in France is seriously so cool. ㄷㄷ
