the only thing that stops me is that I know there are likely to be a lot of shoots and it would be good to leave it like this until I have at least about 5 new clones, in a couple of days I will decide.

I am in a similar situation with one of my succulents. It has some sprouts but the main plant is growing a flowering stem, so I don't want to damage the flowering process by taking out the sprouts. Whatever I decide I will share with you here.

P.S.: The graft looks very "cool".
