Man up and ride advanced.
You are allowed a total of two inverts and two spins in intermediate. They may be repeated, but not in the same pass. In no case will you be given credit for more than two inverts and two spins total. A switch HS BS 180 would bump to at least advanced. A TS BS 180 would also bump you. A switch TS BS 180 is at least an Expert trick. A regular HS BS 180 is worth fewer points in intermediate than it is in Advanced-Pro.
A run that would most likely podium at INT U S Championships would have one invert and one spin each way, supplemented with grabbed 180s and grabbed 2 wake jumps. Add a BS 180 and you're golden.
But seriously, if you have inverts spins, and BS 180s you should be riding advanced.
