imperial bunker conversion ideas

Over on the tactics section Mushkilla posted a thread about imperial bunker shenanigans. In it he suggested turning the bunker into a haemonculi workshop. I could see doing this by lopping off the top so you could model the inside (I don't have one of these so I don't know how hard it would be to put an 'inside' in it) with test tubes or clear sarcophagi (according to the path of the dark eldar books), torture tables, and lots of chains.

However I was thinking of either a crashed or just landed grav skiff with heavy shields (to represent the av 13 walls) and possible a grav lift instead of a ladder to reach the battlements. A heavy Voidlance to represent the Icarus Lascannon and something else to represent the quad gun, and a localized webway portal for the escape hatch.

Does anyone know the dimensions of this thing so I can try to make something like it? Also if you have any ideas to turn this and other imperial fortifications into something more useful than mon-keigh tombs than I'd love to hear it.

I always pictured we'd have something like this in Commorragh. Although I don't see us having Bastion like things unless you have landed skiff like things.

The only other options I could see is repurposing another races building for whatever reason or still functioning/standing from before the fall

Making Eldar/Dark Eldar buildings is something I'd love to do but I always see them as curved structures and that's very hard to achieve short if you're scratch-building. I suppose you could probably find bottles or something similar to serve as a base for the conversion.

As for the dimensions of the bunker, I don't know specifics but it's surprisingly small. I'd go so far as to say tiny. I'd be surprised if it's much bigger than a Rhino.

I was considering trying to see how well 1-2 raiders would do if used for this purpose... but I'd hate to waste two perfectly good transports if it turns out badly.

That doesn't seem like a good idea in my opinion. Maybe a giant floating rock thing that came from the Webway?

A Hollowed out rock? Seems to me like something orks would do... and it would need some type of propulsion to get it In place, as far as I know the dark Eldar can only create webway portals small enough for non vehicles to get through (unless there is an apocalypse web way creater) much easier to design though.
