Read the first page and you'll probably know who he is replacing... I have to say that this replacement is a very bad choice, firstly and this only my opinion, because he is over Falco who I love as a character, even if some moves look like Fox's moves, I still love him, but the last thing and the most important one, is that it seems the item glitch is much more complicated than all other characters to fix, you can fix the item hold glitch, but not the throw part, which is a real problem...
I know there have been a lot of progress over Falco, so it would be very hard to do it on an other character, but if you take the decision to change the character, there is only one character that can match: Ike.
Why Ike? Because he is a right handed swordsman, like Emil. Normally, if we make a character over him, it is possible to put him over other characters as well. He has a sword as an article, which we should probably do for Emil too. And I took a look on his item glitch fix, it seems it is normal, which is not the case of Falco.
So there are two solutions, we change the character who Emil will be over, or we continue on Falco, but if we continue on Falco, go seek for help, because I'm pretty sure it would be much more difficult to work with him.
If the problem is the glitches to fix for Ike, fine, I will fix them, I will even if I can begin this immediately!
Ps: After that, the model has to work with Ike, I don't know if the model itself as it is now can work on Ike, so it can mean we will have to restart from the beginning...
