think you will get different opinions here. There are sound reasons for now or autumn.
i have moved and will still move hellebores whenever I need or want to. they will survive if you accept you will be moving a big underground unit. The root systems on even small plants are surprising. I moved 3 or 4 last autumn as well as one during the summer and all are fine. It is something I do quite regularly
you have a choice......by moving the smaller ones now you are giving the bigger ones time to grow and produce their flowers without interruption. Do it in September and you might disturb the bjgger ones and affect their flowers. The smaller ones will grow better too if moved now. The longer you leave this process the bigger and more difficult it will be to satisfactorily separate the clumps
If mine I would do if now....try to get as much root system as possible but trying too not to get too close to the others.
I would remove bjggest leaves from small plants (minimises transpiration) but keep those just appearing. plant a little deeper and imcorporate compost and water well. Water well too during the summer as they will flag if summer is a hot one.
when smaller hellebores are cleared away give the bigger ones a generous feed and mulch and water.
cut leaves in early autumn for 2 reasons....it does help keep black spot away but it also enable full sight of flower buds emerging and flowers with no leaves to obscure them
sorry aym, you lost me there
