on a much MUCH smaller basis i found that 500g of bio blocks from my established tank made a SIGNIFICANT difference in cycling time.
not exactly the same scenario, i know, since mine were straight from a running filter.
could you hook the new filter up to the existing tank in parallel with the existing filter to help seed it?
are you breaking down your old tank? you could transfer substrate and other hadscape to help speed up the process as well.
