Is it correct to say:
Let's kick around a few ideas of yours.
More common on its own would be "a few of your ideas."
It would be natural in something like this: Well, we've spend the last half-hour talking about Peter's ideas, but I know you have some thoughts too, so let's kick around some ideas of yours and see if we can combine them.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
