As far as I know, there are no plans to change the straps. Although certainly I have heard of customers changing out the included straps with ones that they prefer...which might be an option if you know anyone "crafty".
Actually we do make the silicone gags (without straps) for a couple of vendors that then make really amazing head gear. And I apologize for posting another site here but it's really a high end specialty, at the same time I also applaud that this is probably the one spot where the business doesn't mind that there are other outside businesses mentioned- Mr S in SF uses our silicone gags and puts very high quality headgear on it.
And after all that... I don't see it on the site but you can call
