Eminent Domain - interesting idea?

I was just reading through my Eminent Domain FAQ, and one of the questions got me thinking...

Suppose after you play the action, you leave the card played in play - and it's symbols would contribute to the Role you choose.

For example, if you use Survey as an action, you'd draw 2 cards, then if you also choose the Survey Role, you'd count the icon from the Action card played in the Action phase to determine how many planet cards to draw.

This will really matter a lot more when it comes to Level 2 tech cards. I will have to think about that a little bit and maybe try it for a game to see how it feels. My initial reaction is that it's an interesting idea, but that I won't like it.
