It shouldn't be too hard to port to Lite-C. One of the big things if I recall (I haven't done C-Script in a while) is C-Script is relatively lazy when it comes to syntax, and that often makes conversion difficult, but from what I can see so far you should have no troubles converting. The sooner you do it, the less painful it'll be. Lite-C's also faster than C-Script.

Alternatively, if you want to stick with C-Script (a lot of people stick with it until their current project is over, and then start afresh with Lite-C on their next project), you could have an almost ISOMETRIC view by putting the camera very far away and decreasing the camera.arc (that is, zooming in really far).
