Is it possible to create a virtual pageview from an event using a custom filter?

Is it possible to create a virtual pageview from an event using a custom
filter?

I've released a mobile app (Android) which I track using Google Analytics.
As my experience with Google Analytics is little, I did some mistakes by
not knowing when to use events versus virtual pageviews.
My app has a login and a signup screen and I'd like to track the
conversion rate of users signing up for an account. The app tracks the
page views (/Account/Login and /Account/Create Account) and the actual
login and account creation as individual events (Category: Account,
Action:Logged In and Account Created).
So here's my problem: In order to do a nice funnel analysis, I should have
created virtual pageviews instead of events if the user logs in or creates
an account. Though I can create a goal based on events it will not tell me
the drop off rates in the individual steps the user takes. Only the funnel
visualization can do this AFAIK.
Is there a way to automatically create page views using custom filters in
Google Analytics? I've tried to setup a filter like this:
Field A -> Extract A Event Category Account
Field B -> Extract B Event Action (Account Created|Logged In)
Output To -> Constructor Request URI /Account/$B1
Field A Required Yes
Field B Required Yes
Override Output Field Yes
Case Sensitive No
However, that doesn't seem to work. I do not see any additional page views
or any other changes. Any suggestions?
(Of course I could release an update to the app and I will probably also
do this soon, but the above solution would help me with my experiments
right now - without having to alter the source code every time I have "a
new idea" how to improve the analytics data)
