My advice, in all seriousness, is don't. It will be a letdown. Tilt with the 17 is very difficult to achieve accurately with live view anyway as the gearing is far to coarse, a fraction of a turn, even the pressure of your finger on the knob, will move the plane of focus some distance at moderate J point distances.
As for having tilt lenses prior to Live View, this is true, but they were not 17mm ones and the wider the lens the more difficult the accurate adjustment.
Failing that make some basic J point measurements, and use a tilt table (Northlight has one for the 17mm), it will work well enough.
