doesn't break anything to try raising them but most good speaker makers will design and voice them intending a certain position. KEF for example specifies that stand height for the LS50s should not exceed 24", well short of ear level tweeters for most listeners. The have designed them to yield the smoothest frequency response in that position.
The intended position (which is defined by default for floorstanders) assumes a tweeter height and position from the floor for bass reinforcement. You should assume that they voiced the crossover design to yield their intended frequency balance at the listening position for the speakers placed directly on the floor. in other words, don't get hung up on tweeters below ear level because chances are has already been compensated for.
