I am never going to make weird mpreg features, because, frankly, it is STUPID. However, I will cater to your weird desires to have create spawn from arbitrary sims regardless of incompatibility issues by allowing you to commission artificially incubated simu-drones at the Science Lab. May as well make those rabbit holes do something useful. Of course, there's a few caveats there, too: If, for some odd reason, you decide you want to create your artificially incubated simu-drone from two females, you will not be able to produce any males this way as none of the participants have any Y chromosomes to use to create a male with.
Yes that would be great
