This year is my first producing my own snakes, and it's exciting but I have a question...

I have a Spider female that I want to breed... twice. I absolutely won't do it if it's not possible or will harm the animal in anyway but I searched on alot of sites and didn't come up with an answer. I want to breed this snake with a Pastel and try for Bumblebees (done) and after a break period wanted to try and breed here again before the season is over with a lesser.

Is this bad or at all possible without hurting the snake and what are the chances something will go wrong?
