Can you make a mold from a dildo ?

This is going to sound very unusual but here goes.

Ok, so I have used the clone a willy kit to make a dildo. Would it be possible to make another dildo from that dildo in the future.

Let's just say I am going into surgery in a few weeks. I am going to make a few of dildos before hand, but I literally will not be able to make it again after surgery.

I honestly want to make a strap on but I don't have the time right now. If I can make more from the already made ones later, it's no problem.

If this isn't the best place to post, do you have any suggestions on where else I could get help ?

Thanks!
