Very nice job.
I think a lot of nice stuff may come from this topic especially because some alternative models are shown in the booklet but in most cases they are only shown on the back of the box, so they are very hard to find unless you owned the set and kept the box. The only one problem is that such models have to be built from a single picture so that you may not have all the elements you need to build the hidden faces. On the other hand that would give your job some originality and make it even more valuable for that. That would be fine as long as you use parts which actually are in the set in the right amount.
I hope I also can contribute some way.
