Can you “doublesign” an android apk file?

Question

I did search the forum for a while but i did not find an answer for this. Recently, Google has changed its Maps API for android from v1 to v2. Since i started the project way before March, i was not aware they would not accept new apps working on the old API. Hence, it's just after i finished my app that i realized the Maps API key was tied to the keystore, and i cannot get a new Map API key for v1 now. And i would have to recode the entire thing to translate it to v2, which i cannot do right now.

My question is, is it possible to doublesign the .apk file and submit it to Google Play. Let's say i have a working .apk signed with my debug keystore. However, the .apk will not be accepted by Google because it uses the debug key. Can i then "resign" it with jarsigner to force Google Play to accept it? Will the app still work if i do this? Really would appreciate help for this asap. I don't have a timeline to recode the app now, and i really want to get visibility for the app in Google Play :/

No. You can always sign the APK with any key, but that will just override old key.

Unfortunatelly there is nothing else you can do except just that if you don't have a signing key and Maps v1 API key.
