I think this is a great idea, Grant.
Would you agree, though, that a second Nord-Lock washer would be
appropriate underneath the spacer, as well?
There are numerous 'fixes' including the use of safety wire and folding
tab washers but the fact that the centering fixture must sit squarely
over top of the bolt removes a lot of these options. Additionally, a
second Nord-Lock may create a clearance issue within the cup of the
centering device which may necessitate the cup's needing to be drilled a
bit deeper.
I'll report back tomorrow after I purchase a couple of Nord-Lock
washers. The rotator's on the bench.

Medium strength Loctite is a good idea if the internal threads can be
degreased. Instead of a split ring washer, I use Nord-Locks for
critical fasteners. Check out their video re locking fastener tests.
