Imagine a band called Fun Force.
They would brilliantly perform joyful music and whatever multimedia else.
But there’s a twist.
They can switch to Force Fun for a cynical (or such) side.
T-shirts would have Fun Force on the front with cool positive imagery, and Force Fun on the back with some dismal opposite of that positivity.
As someone with an overflowing artistic plate, I unfortunately cannot realize this particular imagination.
If nature is calling upon you to run talented and competently with this idea, then feel free.
Just do not forget to trademark both Fun Force and Force Fun — apparently at least in the U.S. here by placing “TM” next to the names, and selling a shirt (or such) containing those trademarks across state lines for national protection.
