Pressing claim on an Empire

//ads -- adsterra.com -- native banner

Is it possible for you or someone else to usurp an Emperor title? I married a woman with a weak claim on the HRE to my son (so she is now in my realm as my sons vassal) and killed off kaisers until an 8 year old took the throne, but I still can't press the weak claim even though the HRE is in a regency. Are the conditions for pressing an empire claim much more restrictive?
