There is a lot more than keel shape that matters. My friend's Pacific Seacraft Orion (which has a cutaway forward full keel) lies hove-to most nicely on main only.
My Pearson will lie hove-to on main only or with some jib. However it continues to fore reach at about 1-2 knots with jib out.
The boats (full keel, but small day sailors) that I teach on have a fractional rig with a small jib. They hove-to very nicely with both sails, but you do need to trim the jib quite tightly for it to work or they fore reach as well.
You will need to experiment and find out what works well on your boat.
