(D&D 3.5) Exiled Modron with Adamantine Body

[Lateral]

One of my players wants to play an Exiled Modron with Adamantine Body. I know that, by RAW, it doesn't work, but would it be okay to allow it? Should I make any changes to it?

If anything non-Warforged would be a living construct, it'd be Modrons. I assume the feat itself requires Warforged, though, but eh, close enough.

Exiled Modron, assuming you mean the Dragon Race, is underpowered, so there is no problem with allowing something that makes sense like this.
