Could I apply for an engineering degree with an Econ PS?

So I’ve already applied to 4 econ degrees but I was wondering if it would be possible to apply for Engineering at a uni that doesn’t care or read about PS.

At Bristol I’d be interested in MechEng or Aerospace. Maybe even engineering mathematics?

Which other unis don’t read PS/ reference/ allow me to write a 2nd PS (like Durham for example).

Would this be possible, or am I stretching my chances (this would be my safety choice so no low offer rate courses)?

Stats-wise : 3A*s predicted in Maths, Physics and Econ

And straight 9s at GCSE
