Can a rear stabiliser foil be used inverted as a front foil?

Trying to make a really fast foil for a 45kg rider. Aiming to get to 30 knots. Apart from a Mike’s Lab there is nothing small enough for his weight at high speed. He has reached 26 knots using a 560cm front. Kite racing foils or Frankenfoil?

This is just over 30 knots and the rider isn’t standing.

I know guys riding 390 front wings. Not sure if they are custom foils though.
