TAS was great for Claremontian Magneto fans. Just amazing. As a Magneto fan if they take off from the end of TAS it will be great for him and far better then the mess the end of WATXM made of the character.
Wanda and Pietro were ok though not particularly interesting. They just learned they were related to Magneto and interact with him without any of the Brotherhood era baggage which were necessary ingredients for the House of M to work. As a Lorna fan I don't see how it works for her at all. TAS Lorna was not related to Magneto and while that can be fixed easy enough the character is already settled as a generic love interest character. Being related to Magneto or not being related to him doesn't make her interesting.
I don't think one can get to a Morrison status quo or the House of M status quo based on where TAS ended.
