Hybrid wikihouse floor and wall system plus Light Gauge steel roof?

Hi team,

Would any structural engineers familiar with either light gauge steel or wikihouse have any thoughts on combining the typical wikihouse plywood floor and wall block system with a light gauge steel roof over the top? (Usual straps and tie down rods integrated).

Thought this hybrid wikihouse and light gauge steel roof that makes hip roofing easy might make sense for cyclonic / typhoon wind load areas, where a hip roof design performs better under those high wind loads than the default gable/flat/skillion wikihouse roof?

How to approach this given structural engineers might not be familiar with calculations for the wikihouse system?

System would be required for cylonic areas in northern Australia or South East Asia.

Have been led down this hybrid path as there is currently no hipped roof block system for wikihouse.

Look forward to any thoughts or feedback.

Cheers,

Chris.
