Sailing with a Swing Keel Half Way Down?

[Captrhino]

Could I buy a swing keel boat for lake sailing and for example lower a 5ft draft keel down only halfway ? How safe is this ? How bad in theory will it effect the sailing ? Too much stress on the boats rigging etc ? I'm just cruising , no racing. I like the idea of having the deep keel in case I ever moved it to the ocean.

Thanks
