Can I post a remade version of a code that already exists?

[ComputerBot2016]

I’ve recently been working on a code that allows the player to end a race early by pressing a button activator. I’m aware that JoshuaMK made a code that does exactly this, however, the version I’m working on preserves all racer positions when the activator is pressed (as opposed to the existing code that has a habit of forcing the player into first place automatically). It’s also worth noting that my code isn’t a modification of the current one, it works as an ASM insert over a completely different instruction.

Once I’ve finished testing, would it be allowed for me to post this as a new code? I’ve read the rules for posting codes, but I’m looking for further clarity on this. I would be happy to credit JoshuaMK as a contributor, as I did in fact use an address from his code to help me find the function required by my version.

Thanks
