We use a small dab of crazy glue to hold parts in place and it works very well.

We have begun rotating PCBs in our wave pallets from 15 to 45 degrees. The main reason is to decrease bridging. However, we've noticed a dramatic decrease in lifting and tilting. My guess is that lifting forces are acting on component leads in a successive fashion rather than simultaneously, and the components' weight can better oppose those lifting forces.

You can use wave pallets with a "top catch" which is a top spring loaded pin support for each parts. This will solve your problem.

You mentioned cut and clinch machines but neglected to mention that there is a very popular semi-automatic cut and clich machine still being manufactured. The Contact Sytems CS-400E machine not only cuts and cliches the leads, it also uses beams of light to guide the operator to the correct insertion location.
The cut and clinch parameters (lead length and clinch angle) are fully programmable which makes the machine a great solution for mixed technology boards. With this type of machine lead forming is greatly simplified (and for many components not required).

We have had success tacking (by hand soldering) the component with high temperature solder (Sn10Pb88Ag02) prior to going over the wave.
