That’s it exactly, you might have to experiment with a few different agents/ratios to get them to work but it should be doable.
Here is another paper on a similar idea except for using pollen, it has details about the kind of growth medium to use. It might also be worthwhile looking up the process of embryo rescue, but basically about removing the shell to get at the embryo. Some kind of magnification and micro surgical tools may be the go.
I’m definitely going to be keeping an eye on this thread!!
