Yes, that should be enjoyable and interesting. The future looks extremely bright for Magneto and Wanda in games mass media.
Quicksilver is probably done post Dark Phoenix with any kind of push until the MCU reboots entirely. Lorna has a very narrow window to work as a character as far as the MCU and future games are concerned. I am pretty doubtful they will figure it out, but who knows?
Generally both Quicksilver and Lorna could benefit from a return of the 60s type Brotherhood or 90s Acolytes in mass media and games, not the Fox films era Brotherhood. Quicksilver got into Ultimate Alliance 2 as a member of the Brotherhood if I recall.
