I thought I would go ahead on show the method I use for gluing down the strips of plastic I use to re-scale cockpit canopies. The easiest way to do it is to just glue it in place on one side and let the glue set. Then I glue the rest of it in place. It's much easier to bend the plastic over the curve if you use this method.
Here is a shot of the cockpit after re-scaling. This may not be the "best" way to do this or the way a modeler would do it but it's just for gaming so I'm happy with the results.
I also worked on the "Black Dog" I'm converting from the "Cobra Gunship". Nicer toys like these are often held together with screws which make working on them much easier. Normally I don't go crazy and work on interiors on small ship models but this one was set up really nicely for that kind of thing so I went ahead and decided to detail the hold area and re-scale it for 28mm. 
The cockpit on this toy was even easier to convert because of it's boxy construction. Here I've just added some straight strips to reduce the canopy scale.
The open area on the side of the ship had a boxy bench seat where you could set a couple of three inch figures. Of course this took up a lot of space so I cut it out and covered the holes with these pieces from the Pegasus Hobbies Platformer kit.
Here is a shot of what the hold area looks like after conversion. I should be able to stand several miniatures in the opening or put some light cargo inside. My next big hurdle is the side hatch. You can't see it in this pic but there is a lip on the end of the hatch which looks odd for 28mm scale figures. I plan to make a pull out ramp out of platformer bits that will extend to the ground and look a lot nicer.

Another shot from the front with a Void militia model. The engines are a little tweaked because the support pieces are made from a softer plastic but I think I can fix that.
