Shouldn't have a problem as it/if it,is still taxed and MOT'd but they may well want to inspect it,as its an original plate being removed for the 1st time.
If they do,it will have to have a clear chassis plate or chassis number stamped on it.
They did fully inspect the 1967 VW Karman Ghia I bought and recommissioned to get the reg PLK 1E off it,as they look for obvious signs of possible tampering.
As the DVLA no longer have local offices they may ask you to take it for inspection to a local police station,or if you say its not possible to move it,an officer may come to your place.
Good luck,let us know how smooth it all goes.
