[moved to the Premiere Pro SDK forum]
Yes, what you're asking to do is possible - for example a motion stabilization plugin needs pre and post frames too.
I suggest you turn it into a AfterFX plugin so that it works with AE and PPro.
Use the AfterFX SDK to do that:

In particular, in the AE SDK, the Checkout sample project demonstrates using input frames from different times to render the output frame. It also works in Premiere Pro.
Hi there- I'm looking for exacly what you are working on! I'd love to know if and when you have it for Premiere Pro [CS6], and if you are willing to share for a donation.
PS I'd need a minimum of a 6 frame compounding.
Grimm.Johnny, what about the Echo filter? This will combine frames according to the parameters you specify, including Number of Echos (which you can set to 5, for 6 frames of input) and set your Echo operator.
