How about Eva Marcille as host considering she has done many things since the show including Runway, Acting/ Reality TV etc ...I would say Yaya Dacosta but she doesn't seem like the "Judgy" type and she is busy with TV and Movies ...I think Top Model will do great on VH1 because of the type of Network it's geared towards fashion and reality tv where the CW was more with TV shows leaving ANTM as the only reality show...even though I haven't watched throughly since season 3 I do wish producers would brought on male models earlier in the initial run to capitalize on popularity and had an all male season, girl vs guy, all star and all women ran periodically ...but it seems as if Vh1 core audience will cater to ANTM programming I'm sure Tyra will comeback as Mentor or Grand Judge in some context...Positive vibes for Tyra!
