Can the word "mundane" be used in positive sense

Mundane means ordinary.The word is mostly used in negative sense.Can the word "mundane" be used in positive sense too? Like"Mr.K is not a wasteful man.He leads a very mundane life."Another example can be"Miss ABC does not show off in front of others.She is a mundane girl."In the examples I am referring mundane to be "ordinary" and in positive sense.Can the examples be used? or is it wrong technically?

Solution 1:

It isn't technically wrong, but it's almost certain to be misunderstood by the listener. Consider instead:

• frugal (the opposite of wasteful)
• unassuming
• modest
• humble
• unpretentious

Solution 2:

'Mundane' with the meaning of 'dull and ordinary' (as opposed to 'worldly') is almost always used negatively (or at best neutrally). A positive sense can only be accomplished by a context that somehow makes both dull and ordinary positive qualities.

Replacement by either 'dull' or 'ordinary' might be a good idea.
