My thing here is that why wouldn't they try to make the toys appeals to both genders? Why only get one side's money?

The fun & gotta-catch-em-all mentality of rider gimmicks would not drop to such a low degree that they go out of business. At worst they'll probably end up like Fourze, as far as recent memory goes. And even if it does get lower I doubt they'll end up going bankrupt. They'll just get lower-than-desired income because of the monstrous cycle they've helped created & breed. And no; no business ever wants lower-than-desired income. Ever.

They don't want that yet were dumb enough to not give Go-Busters a collectible gimmick or plethora of auxiliary mecha, which resulted in lower revenue that year as far as Sentai sales tend to go. And that was just due to their own stupidity of making less than their average amount of merchandise. Make a toy line that's very addicting like Gaim's or Kyoryuger's & put in a female main character. That'll at least soften the inevitable girl-drives-away-boys'/boys'-parents'-money blow.

Not to mention the fact that Rider has a much wider age range in their audience than Sentai does in Japan. S.H. Figuarts are proof of that. With a bigger audience than Sentai, plus the fact that Rider tends to make more money than Sentai anyway, Rider is the better option to attempt having a female main character since any loss in sales won't be nearly as damaging as it would be to their other franchises.
