Yeah, but make sure you shim the diffs correctly and get metal CVDs first. Probably not even worth it after all that, lol.

I'd closely monitor your temps because you'll drastically increase your final rollout. A temp gun is probably the single most important tool in helping you protect your investment. Let the temps tell you how to gear your car with the following general limits:

Battery < 120
ESC < 140
Motor < 160

*** check the user manual for specific limits to the equipment you are using, the recommendations here are conservative limits to ensure your equipment last a reasonable amount of time.

Here is the temp gun that I like to use:

hot battery = replace with higher C rated pack
hot motor + cool ESC = under geared
hot ESC + cool motor = over geared
hot everything = WAY over geared

Start with your stock gearing and then go from there... also keep in mind that driving surface conditions, tires, worn bearings etc all effect your temps... always check your temps just like a 1:1 car has a temp gauge to tell you the overall health of your system.

Remember, a temp gun is the single most important tool to own in this hobby. If you have the money to upgrade your electronics, tires, etc, then you should also include the cost for a temp gun without a doubt
