Before I can commit to a layout, find out his tilt/track diameter. From that axis I would think he twirls it a bit.

trace it out and measure across it with a quarter scale.
It will be somewhere between 9 and 13" probably.

What role do the tilt and track diameter play in ball motion?

Tilt and track diameter are synonymous.
Basically, 0* of tilt equates to 13.5" of track diameter. The lower the tilt, the more friction the ball creates per revolution.
For example:
300 RPM and 15* of tilt, will hook quite a bit less than 300 RPM and 2* of tilt.
whereas
250 RPM and 0* of tilt, will hook a similar amount to 350 RPM and 12* of tilt.
As you can see, tilt plays a huge part in what layouts to choose.
Speed, Rev Rate, and Tilt are the critical components of proper matchup.
PAP is irrelevant to knowing how a bowler rolls the ball, but is indispensable to identifying layouts and properly laying out balls. After a while you can get a feel for approximating layouts based on how close the track is to the grip, but that is dangerously imprecise.

For this one, the ball speed and tilt will create friction so the layout doesn't have to be super strong.
55x45@4.5"
Have him throw it before placing a hole, based on what it does we'll figure out where the hole goes.
