"......... I think one is way to large to transplant (I would need a crane
to lift it) .........."

With a beauty like that I would give it a go, shorten the top back well then
try to split the clump into 3 or 4 bits,
When replanting mix peat (Peatmoss) into the soil water well after planting
and stand back.
Lucky you.
