yes I think it is. the crown will provide esthetics till the time RCT is completed.
since there is a periapical the RCT could take time. There could be periapical surgery required.
So the cap can be left in place and changed ( if required) after endo is over.
The only problem is that sometimes there is massive leakage below the crown ( and at times so much so that the whole clinical crown is destroyed) . Than restoring the tooth becomes difficult.
However from the xray this does not seem to be a possibility.
