The first one you posted will not accept a cooling sleeve because of the fins. The second one you posted is a 28mm motor which wont work.

Is there a reason you don't want to use the Hobby King motors I linked you to? I searched that site and other than the boat motors that are backordered, none others will work. Just get the motor coupler for the Brushless Shockwave and you wont need anything else for the drive. You don't have to change the drive wire. Just the coupling.
