Anything like that to fit the cv’s
Short answer: no.
There is not a lot of room for that type of clamp.
Especially on the outer CV.
Personally I have not had too much issue with the stock boot bands.
I know
@JACKAL will go off on a tirade about his experiance with them.
But if you listen carefully he was applying the wrong size band.
So it's easy for me to discount his opinion (just as it's easy for him to delete my post).
The other option would be to get a band winding thing and carry generic length bands.
Don't get too creative with the CV bands.
That is the last place you want getting 'just a little bit of water' all in the name of saving a buck (or saving a minute) .
