Lantana, the Bishop is a large plant. It is also a foliage plant with its purple foliage so delightful even before it flowers.
my view is dig them up, pot them up, put in the greenhouse and start to water sparingly. put in pots big enough to accommodate the tubers and cover the tubers with compost but do not bury the stem. when you see roots emerging from the bottom of the pot then pot on again into a bigger pot but leave outside and start watering well without saturating. i would pot on again to produce an even bigger plant.
my experience is that those little tubers will produce sizeable plants come the summer to fill your allocated spaces
