Idea bouncing/Feedback

So I'm not sure if this is against the rules but I've seen similar posts so here goes. I'm working on pre-planning some early encounters and arcs for a group I'll be DMing for. Have a few smaller ideas that are similar and thought I'd get some feed back. Three main ideas are a turf war over a macguffin between goblins and gremlins on Absalom Station, a Crysmal being responsible for a pawn shop/jewelry store being "robbed", and a rogue bloodbrother is eating maintenance workers/a pack of goblins is trying to hunt it before it kills more of their tribe. I realize these are rough ideas but any thoughts or feedback would be greatly appreciated.
