A local trim or upholstery shop would be able to sew in reinforcing strips with brass webbing eyelets, at any chosen location, which would allow you to lace the fabric onto your skeleton anywhere needed.

Sounds like a big trapeze.

The wheel-houses and inner fender wells will be the focus, as this is where splash and spray originate.

Seems like a stretched-fabric membrane, securely fastened to it's supporting structure, could function reasonably well as a belly pan, as long as its weaknesses are respected in the 'build.'

All, even aluminum sheet, would...should have some focus'd protection from the wheel wells, well secured
leading edges that face especially forward, but also left, right & the rear and keeping it away from catalytic converter & other exhaust piping heat.
...as
Piotrsko mentioned IF a "pond" were to develop, a first inspection drain hole?
