I mean, they apparently have out-of-nowhere changed Heimdall to look like his movie version so I wouldn't put it past them to try and make Brunnhilde into Tessa's Valkyrie, but given that Valkyrie wasn't even named as Brunnhilde and they could just as easily just introduce a new Valk in the same vein as MCU Valkyrie I would hope the former situation doesn't happen.
