Well, what you can do is upgrade slowly starting with the center, then pick up Mains, and use the satalites for the rears. You could also pick up that 12" sub that JBL makes, and use the sub that comes with the Pro Pack as a Sub-Sat rear setup. Of course this can all be done over time as funds allow.

To your question...

Will the center overpower the satalites?

Not if you set up the system with a SPL meter. Then all the levels should match. The center may have more bass, but you can set all of the speakers to small and use the internal crossover for that till you get some better mains to match the center. There lies what could be a problem tho...

The center will no longer be timber matched like the stock speaker.

If it were me, I'd save up the cash to get the mains with that center you want, then it will all match up.
