Land Raider interior kits?

[Evil Eye]

So I'm building a Land Raider for my Emperor's Children. It's going to be a centerpiece for the army, bedecked in spikes, icons and with a daemonic organ growing from the back. So naturally, I want to make it as detailed and good-looking as possible.

 

Now, I'm a fan of detailed interiors, and I do love "functional" details like opening doors. Unfortunately, the Land Raider kit is fairly sparse on the inside- the walls and floor are plenty detailed, but the ceiling is completely undetailed, meaning the leglessness of the commander and the ammo cables of the turret are plainly visible. I have tried to scratchbuild a more detailed interior using, amongst other things, paint pot lids and glue nozzles, but the results are not hugely satisfactory (not helped by my deplorable plasticard skills).

 

So anyway, are there any kits available to add the missing detail to the inside of the Land Raider? If not, how could I best go about building the detail myself? Are there any bitz that could be used, or should I just resign myself to attempting to level up my styrene skills?
