You might be able to load long samples into one of the Reason samplers (NN19 or NNXT). I've not done it myself, though.
The *really* cool thing about Recycle is it can recognise peaks (which are typically percussion) and slice the sample automatically. You can then change the tempo and it plays each slice according to the new tempo, thus keeping the pitch without re-sampling and munging the audio data. There is a device within Reason which will play Recycle files at Reason's own tempo.
I hope you understood all that.
However, Recycle will only accept samples up to a certain length. (enough for a few bars of looped data). So you may need another editor to chop it down anyway.
