I cannot find how much ship weights itself, but deadweight tonnage which is about 200000t. Let's assume 300000t. Thrust of Saturn V S-IC stage is 3300t, with diameter of 10m, empty mass of 130t and 2150t of propellant for 150s burn time. It would need nearly 300 fully fuelled S-IC stages to lift it! Which is a bit too much, as with 400x60m ship area we can only fit about 240 stages. But as we're definitely not going into orbit anyway we can reduce propellant amount for shorter burn time. Cutting propellant by half reducing burn time to 75s we only need around 143 stages, fitting on ship with room to spare.
So in that regard it is doable. But there's problem of what to do with all the exhaust, as rockets obviously aren't designed for pulling load attached to the bottom...
