I guess you have a large bedroom...
Taking a finished speaker design and swapping out components is always a recipe for frustration (unless maybe you can get identical-spec replacement units from the factory.)
Cabinets and crossovers, if properly designed and built, are meant to go with the exact same driver complement and cabinet. Slipping in new same-sized components (to fit the cabinet) doesn't mean they'll just work. However you obviously know this because you are ready to provide a new crossover.
Wow. OK, then. This would be a one-off project. You will need a speaker building expert. Do you have complete specs on the drivers, crossover and cabinet? That would simplify things but your expert will still have to measure the components and systems to make sure they work as specified. Then he (or she) can take the measurements and look for suitable drivers. Then he'll design a crossover to work with them, buy the parts, build and install it and start the listening tryouts.
This last stage could be long or short. If you want some info about it, go to George Short's North Creek site and read up on the design process he describes for some of his models.

The process requires time, deep pockets and more than a bit of luck but anything else would be hit or miss, with a very high chance of a miss. Most folks who try it run out of motivation somewhere before the project is done. Their speaker never sounds right, gets dumped, parted out at giveaway prices or winds up looking for a pigeon in a pathetic ad on kijiji.
I don't want to sound scornful but I would never encourage anyone to try it unless they were already experienced speaker builders and knew just what they were getting into. Myself, I would spend the money on a new speaker--one of Mr. Short's kits would probably satisfy my DIY itch.
All the best anyway if you decide to go for it.
