Possible merging

Frustration in Excelsis
Notoriously Divine Tagger - Consistently uploads images above and beyond the minimum tag requirements. And/or additionally, bringing over the original description from the source if the image has one. Does NOT apply to the uploader adding several to a dozen tags after originally uploading with minimum to bare tagging.

I wanted to ask if these two images should be merged:
 
 

 
They’re largely the same, but the second and more recent one (an upload I made just now) doesn’t have the large, visually obstructive logos on it. My question is, then, given that Rarity’s and Spike’s poses are slightly different in the two images – are they similar enough that we don’t need the both of them and one should be merged into the other?
