Re-Uploading all your old SIMS CD KEYS to EA?

IF The SIMS decides to do conjoined worlds, to allow SIMS2 Worlds to exist beside SIMS 4 Worlds, etc. I would like an option with our EA accounts to enter the CD KEYS from older versions and the CD Keys for all the DLCs so we do not have to re-purchase.

We have an entire bookshelf here of SIMS titles and all the DLCs. I think we even have our four copies of SIMS ONLINE still.
