My solution turned out to be modifying the actual D cell holder itself
and not touching the battery adapters. I simply screwed in a couple of
bolts with head sizes larger in area that the original positive
terminals. Then, cut off the thread part of the bolt ends and sealed
off with liquid electrical tape to offset any short possibility.
Problem solved.

By the way, some suggested using the right battery for the right job.
To my knowledge, Eneloop doesn't make a D cell. Others do, but I only
trust Eneloop. They do have multi AA to D adapters, but for the small
amount of current drawn, I went with a single AA to D this time around.
