Firstly, BG doesn't have any MUs that are 'very difficult' for the opponent. They're all either even or 6-4 (slight advantage).Sorry bit I think you underestimate batgirl...from your pick it looks like you main her and know her better than me but I doubt you've ever had to fight her as a very difficult mu, getting rid of her meterless vortex would put her in like with everyone else as NO OTHER characters have it, she'd still have the same vortex just less meter in her pocket. It would make her like frost and lex in a way as they have great vortexes that require meter, this is just my opinion though
Secondly, the way that bola is structured and they way her character currently works, it would be impossible to modify her design so as to make her require meter for vortex. That's what I'm saying. They would have to remove the launching properties of both her overhead and low starters, which would constitute a massive nerf and place her in F- tier. There is no way they could institute a meter requirement without this. Bola already has a meterburned version, so that's out of the picture, she can get the vortex off ji2, 111, b2d3, 21 or whiffed normal, so they can't do anything to her strings to require meter too.
Also, Sinestro has a meterless vortex (as does WW in the corner).
