I have had a particular six string electric guitar for a few years now, I have it tuned to drop B using these strings,

However I do not use drop-B much.... while I enjoy occasionally playing in drop-B, I do not listen to or play much much metal these days. Hence it remains in the closet.

I would like the option of occasionally tuning to and from drop-B, so I do not wish to use lighter guitar strings. Would it harm the guitar if I were to tune it to standard/drop D using the strings cited in the link?

That's fine. You might have to make minor adjustments to the truss rod to get everything where you want it, but that's about it. 10-52 is great for what you want to do.

This is terrible advice. Even worse than the useless dry, sarcastic comment I made.

Yeah, I had made bridge adjustments for the drop B. I think I can reverse it easily.
