There's nothing wrong with doing a large water change during a fishless cycle as long as you recharge the essentials (ammonia) and understand that the numbers may be a bit wacky for a few days. After all, its the bacteria in the filter we're growing and the tank is nothing but a big reservoir of "bacterial growing soup."
I think your plan to switch is very sensible. Most people do choose to use their newest and largest equipment for their main community/show tank. I think it would be good however (given a bent in the impulsive direction we've just witnessed) to keep in mind that fledgling bacterial colonies (even big fully cycled ones at 2 months) are still fragile enough that they can be significantly disrupted by things like filter and tank swaps. We all read of lots of mature media being moved around on this forum but we don't read as much that the most successful moves involve very old, very mature media and sometimes that new, immature media gets badly set back by moves to new filters. I'm not yet proposing a plan, just want you to keep that in the back of your mind as you continue the stable environment of the bacteria you are currently growing.
