Convert Mortice Lock to Cylindrical Lock
Short answer, no.

The new lock is a cylindrical type that requires a standard hole in the door, usually 2 1/8", set back a certain distance from the edge. Most mortise locks do not have that size hole, so it must be drilled with a hole saw. Also, the mortise mechanism must be removed and the door needs to be filled in where the mortise has been taken out to hold the latch mechanism. A hole for the latch will also have to be drilled into the newly built up edge.

You also need to remove the existing deadbolt from the bottom and replace it with a cylindrical type deadbolt. Again, the hole may be different and the mortise channel must be filled and drilled to hold the bolt mechanism.

None of this is very difficult, but requires the right tools and some patience. Care must be taken, because misdrilled holes in a door are difficult to fix aesthetically.
