Akhelian Leviadon and Tantalus size comparison

I've been looking at the Namarti model line and the Akhelian Leviadon got my imagination going with how it might look with some Coven modifications. Due to the rather small choice from Coven heavy supports, I immediately thought Tantalus.

I am curious, how large is the model? Does its size compare to a Tantalus, or is it much smaller? Has anyone seen both of them in their local games shop to be able to make a comparison of the two?

Have you had any luck finding answers to your question? I want to pursue the same conversion!

Judging from the people on top, it would probably better serve as a raider or larger-than-normal venom

A kind Instagrammer told me the following dimensions of the leviadon:

26cm length
20cm width
20cm height (base to tallest point)

I don't know how accurate these measurements are though
