At this point it is illegal:
Rule 3.7.2.b requires that there is another catcher when they land after doing a skill. The catching part is considered to be a dismount.
If the dismount involves a skill (e.g., toe touch, twist, etc.) two bases or a
base and a spotter is required, and the assistance must be sufficient to slow
the momentum of the top person.
It is defined as a toss – see page definition page 12 NFHS Spirit Rules Book
