Dreamforge Leviathan weapons on a Knight: 15mm or 28mm?

[Ovidius Incertus]

So I'm conceiving of another Knight project (like I really need another one!) and am interested in using weapons from a Dreamforge Leviathan.  Of course, the 15mm scale Leviathan is too small for the Knight and the 28mm is too big.

 

I've searched for examples of Leviathan weapons on a Knight and found a few things to look at, including a thread here.  I had trouble determining whether they were using 15 or 28mm weapons, because all the examples (specifically the Leviathan claw) were pretty oversized.  One thread said 15mm, but it still seemed way big for the fact that the 15mm Leviathan is 2" shorter than a Knight.

 

Any thoughts?  How large is the 15mm claw hand in relation to the fist that comes with the Knight?  What about the scythe?

The Leviathan weapons are hugely oversized. I don't have any pics at the moment, but for a quick and dirty comparison I believe the 28mm mauler claw is about twice as large as the GW knight power fist. The guns are similarly humongous.

The Leviathan weapons would be too big. Might work an a Cerastus Knight as Leviathan's are a bit smaller than a Warhound iirc, but not the bog standard plastic Knight.
