You're asking for us to tell you how you can make a group of four siblings based on the seasons, without ripping off the Four Maidens.

Simple answer is this: there is no way. That is literally the core behind the theme of the maidens. It's like asking how you can make a character who's based on Little Red Riding Hood with a scythe weapon, without seeming like a rip-off of Ruby. You just can't. It's that simple.
