You might want to consider registering to a mid-way point and thus move both the same amount (but in opposite directions essentially)

However, I have realized that the registered T1 will be slighlty blurred relative to the reference one, beacuse of the resampling occurring for the registration. Should I blur to the same extent the reference T1 ? And if this is the case, how to calculate the amount of blurring ? Can I just ignore the fact that the registered T1 is blurred ?
