Certainly.
I would love to be the one to rig this model of Roy...However, I still have things that I must bring up about him.
~~~Big~Post~Ahead~~~~It's unfortunate about the hands, but I could probably vertex them and attempt to match them to Marth's positioning better like that.
I would prefer to attempt using the Melee hair still. Admittedly, it does look a bit odd, however, it can probably be vertexed to remedy this.
I would hope that it either has a higher level of vertices to manipulate than the vertex's hair, or at least more freedom as opposed to how Marth's hair is made of 5 or so polygons.
However, if even then it turns into disaster, the vertex's hair will have to do.
Also, based on the render you did not put the face on him I had sent you.
I had vertexed all 5 faces of Roy(it was on one of the two models I sent you), as they all had deformed eye sockets(As well as the left eye, regular and FS, a random vertice spike on the back behind his head, and one of his ears). With my textures, the irises would be even with the bottom of his eyelids during his default gaze and both eyes would be the same size and shape, whereas one of them from the render appears larger and more ovular than the other.
I did copy and paste the digits to ensure nigh perfect symmetry that, I assume, was not lost with my patching :3
Now, I certainly don't want to start any sort of a conflict over this and normally I'd just walk away and let things slide...But I am afraid I am correct about the sheathe's positioning and facing.
And I have some pictures from Melee, as well as a clip of his win3 animation to back things up;
Forgive the quality, these were taken via a 3DS's camera function from the actual retail disc of Melee. But I feel they still get my point across.
This shows the positioning of the sheathe on his Classic mode trophy. All 3 trophies possess the sheathe and they all have it in roughly the same place. Given where his sword's hilt is positioned is relative to the positioning of his sheathe. If it were attached via the metal gizmo like in Melee, it would be a little bit left and down from where his belt buckle is on the other side of his body.
This one shows which way the sheathe is facing. I'm afraid that your render actually displays it being attached backwards.
The larger, more "obstructive" part of his sheathe, circled in red, is supposed to face his body, as that is where the metal gizmo is attached that hold the sheathe onto the back of his belt.

Melee trophy showcase, in case it helps. Roy's trophies start at about 5:26
As far as drawing the sword from the sheathe, it is perfectly reasonable.
Given how the metal thing attaches on the part that would appear obstructive, it really isn't given how much closer it is to one's body. In real life, much like the attack using it in FE6, it would pivot at the point of where it is attached, and using one quick motion of the arm, it can be unsheathed.
I will demonstrate in this vid;

As you might've heard me say "Getting it back in is always the hard part" Which, in contrast, it would be. Unsheathing a weapon is always easier, even without looking at it. Like a child and socks.
It'd be more of a realistic animation than Link and his sheathing. Every time he pulls out the sword, it is essentially cutting its way out animation-wise. Believe me. I know swords, and his is too long to work realistically with his sheathe setup.
The most unrealistic thing about this sheathe would be keeping it on him like that for actual combat, I find.
Given how it attaches and how it pivots via the metallic thing(like his attack with it in FE6) combined with the length of it, it would keep hitting him in the back of the knees. Again, something I know too well from my Roy costume x__x
But even Marth's sheathe I find is...Unreasonable to wear into battle, given how it can still freely jiggle around and hit his legs.
Roy's sheathe is awesome, but impractical : /
