And no, you won't burn up the receiver due to the supposed higher current with HV servos. For a given amount of torque, a HV servo will draw a little less current than one rated at the same torque at 6V.
The question as to whether there's a problem with too much current for the receivers power bus is determined by how many, and what torque ratings the servos have and other factors.
