Here it is. Host, if you need to add anything else, just shuffle the added bits to where they should realistically show up in terms of invention it's all chronological. Early game should be slow but you can get the first decent coasters by year 5 (side friction, virginia reel, wooden coaster).

It'll overall be a bit of a slower burn game than usual and probably end up with 'eras' of park construction. If the loan interest needs to be adjust mid game if this is too much early on then that should probably be done. Other than that I think this should be a usable park.
