Crazy idea here: What if you make this a contest? You could import your Sketchup work into a park file as a template and have the whole community work with it by submitting layouts by a certain date (say April 15th). You can put as many constraints you want in the contest to fit your previous work (like making it an Intamin hyper like your website suggests) and choose the one that best fits your vision. You can then work with the winner on making improvements and adjustments as you add details to the in-ride scenery.
That being said, are you sure you're 100% sold on the Intamin hyper style? An Intamin blitz would fit Mad Max better thematically (especially with the idea of driving through various canyons and staying low to the ground) and works better with the lineup of WB Movie World, since they just installed DC Rivals. The 8-car station you made could also fit a dual-load station like Maverick, and a 4-across blitz would be fun to work with. You could even add a second launch and make a mobius layout that races.







I have even been adding support made anti rollbacks where the hidden brakes are for the anti rollback sound. This wooden coaster has 273 block segments so far.
