The trouble with using a full size servo is that it is too long and will have trouble getting the pinion in there (assuming your motor will be mounted on that side). Also, the servo horn will hang out further over the side. The only way I can see it working is if you either get an extended chassis or cut the servo mounting tabs off and use servo tape to hold it there - but then the servo horn is still hanging off the side...
