Two souls permanently becoming one...

[Aloysius]

In my opinion
When things merge the product is usually greater the the sum of its parts. If you were to truly merge you would not simply be adonai+other participant. There would be interaction of existing properties within both parties producing new distortion, it would be a third being (lol like having a kid). Either that or you're talking about sinking back into infinity, I'm not quite sure...
Temporary merging may be something to play with first, permanent sounds so final lol
Yeah construction and deconstruction are just rearranging potential structure, transformation, but it sounds like awareness would be lost in the process, not to be a naysayer but that is honestly what it sounds like.

Then again I guess it would depend on the inherent differences between the individuals involved.
