So like what if you crocheted a piece of fishing line paired up parallel with the yarn in a couple rows, then could like pull that tighter to introduce some tension from a few different angles for support? I don't know if that's at all practical  

 It could work. Floral wire or armature wire of different strengths are the usual solution, you crochet around it and the yarn becomes bendy.  

 I dunno, seems undercomplicated. You're the pro here though  

 😂 less is more sometimes.
