This is never an easy thing.  I MIGHT be able to do this IF:

• You have a largish printer and there is an open space on the build plate where the Z can be zeroed.  Remember that the gantry will be lowering with a print on the build plate.  A back corner is the best spot.
• There will likely be a slight layer shift because the X and Y endstop switches aren't perfectly accurate.  After homing the X and Y - the new X0 and Y0 may be in a slightly different spot in space than they were at the start of the print.
• I would need the gcode file and the exact layer number that you want to continue printing from.  It would be the "Cura Preview Layer - 1" to equate to the gcode layer number.
• Any variations on the top of the model (splotchy extrusions that occurred before the hot end clogged completely) would need to be cleaned up so the "resume" layer doesn't whack the model and break it loose from the bed and the plastic of the resume layer has a good surface to stick to.

Good luck.  I've done this, but the best situation is to catch the problem right when it starts, and abort the print.  If you are able to do that then you know right where the print failed and can avoid the bad top layer on the print.

The STL file isn't enough certain settings (layer height in particular) need to be exactly the same as they were in the current gcode file.  Resuming at 93.15 is not the same as resuming at 92.8 although both are very close to "93mm".
