i think it would depend heavily on the audience and which story got adapted coz of the main three i'd been developing i can see maybe two being fairly well received but the third would likely end up with a kind of small niche fanbase because of it's content
coz there's the option for the character driven fantasy adventure with enough of a mix of action to keep people engaged, there's the supernatural/fantasy slice of life with comedy and drama elements and then there's the experimental supernatural drama
plus my mindset is that if something as esoteric as lain can earn it's own dedicated fanbase then i've got nothin to lose
