That is not possible with Time Machine. Each drive you use will contain a full backup of everything that's not on the exclusions list. Besides which, that wouldn't be a great strategy anyway... It would create a situation where a failure of either drive would be sufficient to compromise the entire backup, spanning both drives. What you really need is a larger backup drive. (And then another larger backup drive for a secondary backup. )

There are ways you can continue using the TC by just adding a larger external drive to it. See:
Note that third-party NAS drives won't work reliably with Time Machine, and neither will a hard drive connected to a wireless router (even an Apple AirPort base station). As long as you've already got the TC, you might as well continue using it in conjunction with a larger drive or hardware RAID setup.
