DropZap 3 rejected again on appeal. What should I do?

DropZap 3 was rejected because the DropZap games were considered similar. Apple suggested combining the DropZap games into one using In App Purchase.

I appealed the DropZap 3 rejection but was informed today that the appeal was denied.

Should I remove DropZap or DropZap 2 from the App Store to try to get DropZap 3 into the App Store as is? But what if I want to release an update for a removed app? How would users react to a removed app?

Here's the text of the appeal that was denied:

Please reconsider the rejection of DropZap 3. DropZap 3 has by far the coolest gameplay of the three IMO:

It has been recommended that I combine DropZap, DropZap 2, and DropZap 3 into one app using the In App Purchase API.

But there are problems with this.

If I use the In App Purchase API in DropZap to provide DropZap 2 and DropZap 3 gameplay, what would happen to DropZap 2 which is already in the App Store? Whenever I would make updates relating to DropZap 2 gameplay, would I then update both DropZap and DropZap 2?

I don't want to increase the price of DropZap 2 or DropZap 3. If the way to purchase these is through DropZap, then the customer would pay for DropZap and then again for DropZap 2 or DropZap 3.

Also, DropZap provides two methods for global scores (my own + Game Center). DropZap 2 and DropZap 3 only provide Game Center. My custom method is laborious as it involves me manually checking submitted nicknames and I would rather not use it for DropZap 2 or 3 gameplay. Removing my custom method from DropZap is problematic since not everyone can use Game Center and so it would be like removing a major feature from DropZap.

Finally, DropZap provides three graphics styles, but I only want to use one for DropZap 2 and DropZap 3. Users may expect to be able to use all three when they purchase DropZap 2 or DropZap 3 gameplay.
