Hardware GBA Micro to SP DIY Link Cable?

[abcdaaabbbcccaaa]

So I've got a buddy who's got an SP, and I only own a micro. We've been wanting to play together, but I've recently found out that the adapters between SP and micro don't exist anymore, anywhere.

But I found this diagram:

and so I realized that technically can't I just take a normal GBA micro and SP link cable, cut both, and solder the wires accordingly? Would it work, or does the adapter that Nintendo made have some kind of tricky wiring to it or something?

Yes, you should be able to do so.
