Need a bit of help with creating some jump ratios

I got hired to be head park crew at a local hill and id like to sort out some ratios for a jump before so i got a plan for the build day

my goal is to make a 20ish foot step over/turtle shell jump (the tip of the take off and the Kunkle are at basically the same height) I understand that the ratio should be more of a 1:1:2 with takeoff length being 20 then distance from take off to knuckle being 20, then finally landing being approx 40 ft. my issue is I'm not too sure if a turtle shell would have a differing ratio for flight deck plus takeoff and what the angles for the deck, takeoff, and landing should be.

Any help would be great thanks. also if you think that a turtle shell jump is not the greatest let me know and let me know any other ideas you may have.

ps the goal is kinda like the jump at Tremblant park (if anyone has picture of that jump send em my way please) from these past weekends just slightly larger and a steeper landing.
