I can't imagine a soft ban happening for that. At least for me, the execution requirement on these infinites is a bit too extreme to ever worry about it enveloping a competitive environment, not to mention they tend to require really specific setups off of, at the very least, a hard knockdown and some sort of mixup.
You might also enjoy Aoko. She has two airdashes as well and a lot of neat tricks, gimmicks, and projectile options. Shiki Tohno and Nanaya might also be to your liking, as they both, while lacking in air mobility, tend to have extremely fast ground options and amazing normals. And, like TheMaster_Rahl suggested, Sion and also VSion I'd say have a similar feel to Bang and Yosuke in a few ways, although they tend to have some really stubby normals.
