I think it's a great idea. Of course, one of the team might want to OK it, too.
Personally, I think doing it in blender will be difficult. If it's for an in-game model, most of the detail will be in the textures, and you'd end up drawing everything anyways.
If it's for a high-detail still, then there's still a lot of work to go into it anyway. It's a hard project, especially if you're new to blender.
And as far as drawings go, you can take advantage of that and make a non-photorealistic drawing. Maybe like a pencil sketch, with false colour to show things like different muscles and organs.
Of course, you're the biologist, so you know much more than me about how the whole process works and how insides actually look.
