I personally would not bother building an engine that did that but others have done it and gotten away with it.
No technical service manual on the planet approves of it.
Used means loose. Bad idea on crank as the crank being loose then lowers oil pressure to the rods and then they spin.

Physically yes they fit but honda has 4 sizes/color bearing shells. You have to do measuring or at least plastigage to see what you need for bearings. I have mixed and match new and good used bearings to get the exact clearances I needed. Used does not necessarily mean loose it just means used. I can put new wrong bearings in and it can be loose, I put put the wrong color used bearings in and it can be tight. Its all in the clearances not whether it is new or used.
