Hey Sharla
Rider is an extremely positive card, and so it is hard to imagine that it won't lighten the Cross in some way. My method for reading with the Houses is to use it like the first card in a two card spread, so - Cross/Rider: Someone helpful is on the way, or someone will arrive who is spiritual, or a guest that is destined to come to see you
So yes, I would have thought that it is something "fated" to happen. Your corner cards are quite nice! Especially as you did 9 x 4, because the Stars are in Bouquet - sweet! Looks like things will be improving for you.
It did also occur to me - in regard to Cross - that it might simply just mean a responsible person (Rider can be somewhat immature as a man, and so the Cross gives him a bit of dignitas - a young man who has a serious head on his shoulders).
