With all the pre bonding you are doing you are already on the right track.
It’s definitely worth waiting a bit longer for Lola to recover as you said before you try too much.
With trios and larger groups of rabbits it might be worth just trying a few different bonding options to see what works for them. You can try play dates with pairs, or all three. I personally did pair play dates a couple of times to see what each rabbit would be like with the other, and then focused on the pair I thought would be the trickiest before doing all three. You will also find out soon enough whether stress bonding will help you or make things worse – I know a lot of people who find it helps, but I have a rabbit who gets aggressive when stressed, and even neutral territory stresses him, so I actually have to bond him in his own territory – then weirdly enough he is fine and super friendly. He is now in a group of 4.
