The strings are not hollow afaik and I don't think you'd have much luck with that idea.
They break however you play them and I see it as an unacceptable design fault, I keep strings on my electric basses for up to 15 years and I've never had one break in over 30 years playing.
I changed to pahoehoes on my Ashbory and never looked back.
If the pahoehoes had been available when the Ashbory was designed I am sure they would have come as standard and I don't know why they are not available as an option when buying a new Ashbory, unless it's something to do with Fender's profits.
I think the issue is with the patent on the strings, ashbory basses (or any bass) sold on the market, is obliged to use a certain shape and length of bass guitar, if they want to use rubber strings. So I guess that when you buy an ashbory bass, you're actually buying the only design of bass that is within the patent of the strings, in other words, you're buying the strings with an ashbory device around it (or something like that)...
For me the big turndown is the shape of the bass.
Anyways the rubber/silicone strings sound different. If they could toughen up the strings a bit, perhaps then they would break less...
Where do you find them breaking most? in the middle, on the place where you play them with the right or the left hand (pickup or frets), or on the bridge, or nut?
I suspect if most strings get destroyed on the nut, perhaps it would be a good idea, to put some powder in the string grooves?
