There are problems inherent with merely changing the tempo of an already recorded drum track.

When a drummer is playing at a slower tempo, the kind of fills used are typically going to be "more busy".

Likewise, faster tempos, the fills and such will be a bit more sparse in nature.

Speeding up a slow drum track only works to a certain degree and at some point becomes "busy" sounding.

Slowing down a drum track that was recorded at a faster tempo, the fills become dreadfully wanting.

I think the real answer to your problem would be to choose another RealDrum file -- or perhaps some more RealDrums files that have not been made yet, that can cover the halfime/doubletime situation properly.
