Need Center and Surrounds to Match Focal Sopra 3

I have a dilemma. I overspent on Focal Sopra 3s which are awesome.  I was using them for 2 channel music and now I’m going to use them for my home theater (music and movies) and cannot afford the Sopra 3 center and surrounds. I regret spending so much now, but I’ll lose a ton selling them used, so I need to figure out an affordable alternative for a center and surrounds.  I don’t believe that I MUST buy a Sopra 3 center and Atmos set up for it to sound good, but still want to get something high quality. Can anyone please help? I’ve looked for used Sopra 2s and 3s and have found nothing. Thinking about high end paradigm center? Other than that not sure. Please help. Sopras have a berrilym dome tweeter, but a match is not a must as they sounded fine with my monitor audio silver center, which I’m now going to use in my living room. Thanks much!!
