Open F6 operator panel automatically after pie operator?

Is it possible to call the F6 operator panel (in python) after executing a custom pie.operator? I’d like it to pop up after certain commands where I almost always edit parameters afterwards (such as remove doubles).

Bump! Still looking for a solution…

Create a class operator, add your command ans the f6 command.
Call this operator in the pie operator.
I don’t have test it, I will do tomorrow.

if you try to chain a modal operator and a non-modal operator, the non-modal’s execute() method will be executed before the modal operator’s execute(), so it’s pretty much useless

Thanks for replies!
So its not possible to bring that info up at all (as pitiwazou suggests)?
