Since ice is a crystal, you can build a crystalline unit cell by hand (the unit cell will have one or two water molecules, so it's pretty easy to do it by hand, you just have to be careful to use the same atom ordering as the topology) and replicate it using gmx genconf so the crystal has the dimensions you need.
