Surfing Pikachu and Altering HM Overworld Effects?

Hey guys. I've been messing around with a few ideas in Pokemon Gold, and I've been trying to figure something out. Bear in mind I haven't learned ASM.

Where would I go to edit the effects of HMs in the Overworld? For example, is it as simple as changing a few values in a hex editor, or is it more complicated than that?

For example, could I take a HM slot like Whirlpool for example, give it an overworld effect of Surf (while using the old standard hacking programs to change it's battle effects), and rename it? Basically the idea is like an alternate fire-themed Surf, for crossing lava in caves. Technically either type of move would allow movement on the Water/Lava tiles, no matter what Pokemon/Tile it was, but I like the idea of having two different moves.

However, I have noticed it's possible to load an alternate sprite for using Surf with a Pikachu. Where is the data stored that checks that it was used by a Pikachu? Would changing the Pokemon who triggers the alternate surf sprite be as simple as changing a hex value? Could I feasibly use Surf (or it's potential Fire counterpart) with Charmander and trigger the Surfing Pikachu sprites?
