This is how you end up with 4 rabbits (like me! lol).
So, I would just treat Skittles and Loki as your bonded pair, and stop having Loki interact with Luci face to face. Since it’s pretty clear the girls are not compatible and a trio wont work, there’s no real point to having them interact regularly.
In my experience, F-F pairs are tough. There are cases where it works, but it is often really challenging. So I don’t think your girls’ failure to bond means that Luci isn’t bondable.
Do you have space/time/resources for a fourth rabbit (including during the bonding process)? Are there any rescue organizations near you that do bunny speed-dating or allow people to do “foster to adopt”? Some rescues will let you try out a bunny for bonding and then swap if the pairing isn’t working out.
I had a somewhat similar situation where I had a pair, then fell in love with a foster (Bonnie). Tried to bond a trio, that didn’t work (the girls weren’t getting a long at all) . Then tried to add in a fourth to be a quad, and then boys weren’t getting along AT ALL, so I ended up with 2 pairs, which are both very happy.
