Scott-I looked into that way but the Tomahawk Futura was setup that and we had alot of flipping of the geometry when pushing the model around with the power off (nose wheel rotating enough to flip the servo arm the other way). So far it seems to work as is, doesnt turn, and has enough throw. In one of the last pictures posted you can see my neutral position of the servo and retract arm with the nose gear retracted.

John-Several reasons for the overkill actually. I lost a preowned model several years ago to a bad steering servo on takeoff. Totaled it. For that reason alone I no longer skimp on the steering servo. Taking off and landing is a dangerous activity for the model and spectator and I enjoy the extra peace of mind I have by having a top shelf servo on that function. The rest of the model is also run at HV which, to some extent, limits servo selection (not the Hitec you mentioned). The final reason is I try to build these sport jets with the same servo on all surfaces so that I essentially am always carrying around a "spare" servo. I've been at meets before and have had primary surface servos go bad without a suitable replacement available. Although I try to carry spare servos around with me now I know at the least if something were to happen to an elevator or aileron servo I could just pull the steering servo and use it on the wing without compromise.
