That would take an awful lot of fuel
Other than the heat shielding itself, aerodynamic braking is an essentially free way to dissipate the kinetic and potential energy from orbit. It'd take an awful lot of propellant to use thrusters to bring the thing down all the way. Even the Delta Clipper concent used aerodynamic braking for about 99% of the slowdown, with thrusters used for the initial deorbit burn and final touchdown. A lot of people complained about the amount of propellant required for the landing since it was essentially additional dead weight for launch.
