Replacing aquascape with new rock. Thoughts?

[RiverChad]

Hi, so my system is 3 years old. I'm getting really tired of my current aquascape and was thinking of building a new one and cycling it in a brute trashcan after I glue it all together. If anyone has done this is there any tips or tricks you can pass along? How long should I cycle the new scape before throwing it in the display? Is there any risk of a tank crash if I remove my current aquascape?
Also is there any parameters I should maintain in the brute trashcan while the rock cycles? I know parameters will drop on their own but is maintaining them any benefit to the cycling process or bacteria that will be growing on the rock? Thanks

I'm not sure if this is possible, but are you able to instead keep the rock in your sump, then slowly replace the pieces in the display over time?

Unfortunately I don't have a sump, I'm using a 38 aio peninsula by water box. Given your answer I'm going to assume this is a bad idea?
