Aftermarket wheels...how safe are they??

All are DOT approved. Probably inspected by design and material only or sample inspected. Worried? Just run plastic rims..yeah!

Don't think this has been tried before? Mopar did it too. The deep 5-spoke propeller looking wheels on the Dodge Shadow (IIRC) were compressed fiberglass.
