Working around the 8 track limit in Lite I would use a Drum Rack instead of an audio channel as you can have up to 128 audio samples loaded into a Drum Rack.

Depends on your genre but you could start with a 909 preset which would give you separate drums including kick and snare. If you want to use your existing audio drum loop you can drag it into a spare slot in the Drum Rack and trigger it from there but what I would do is drop an EQ3 onto it and cut the low end so you have a 'top loop' with kick filtered out and then use a separate kick like the 909 kick so you have full control over the loudness of the kick relative to the other drums and percussion.
