You might be ok with your existing engine. You'll need to take the cylinder head off, the rest of the engine can stay in place.
When I had broken exhaust studs on my FZS1000 head I took it to a specialist garage where they performed some sort of electro-welding to get the stubs out without damaging the threads. I assume such specialist shops would be able to do the same with a disintegrated spark plug.
While the head is off you could then check for any debris in the cylinder, or even drop the sump pan (after draining oil) to be sure there's no metal anywhere.
There are of course 2nd hand cylinder heads / barrels as well as engines should there be major internal damage.
