I've got the G1 and the E-P2 here - just done a side by side comparison of the EVF view through the kit lenses.
It's true the EVF on the E-P2 is a nice step forward - significantly better than that of the G1, especially in low light where the faster & smoother refresh rate, along with less noise makes it preferable.
The rubber ring on the VF-2 will come off, so it's just a case of finding a replacement eye-cup which would adapt to the hard plastic lip...
Here's an illustration (sure to be 'recycled' shall we say, so may as well advertise our forum

) :
