Center channel for ls50 metas?

I recently acquired some used LS50 metas for a very decent price. I am currently running them in a 2.1 configuration with an SVS SB-1000 Pro sub and a Denon AVR x1700h. Conventional advice would say to get the ls50c, but the physical profile is not super desirable to me in my current configuration. And there is a decent chance that I may upgrade the front right/left speakers down the line and make the current ls50s rear surrounds. Is the r2 meta a sensible center channel speaker for my current configuration? Will it be too different and not offer much benefit. It is my understanding that the driver is quite similar to the ls50s; so would the timber, or anything else, be horribly mismatched? Any other suggestions for a center channel for my confguration
