I did these optimizations about 15 years ago and both, if I recall
correctly require boom extensions and a Phyllistran support for the
boom to the mast to reduce the boom droop. I can't say that the work to
do this was worth .5db of gain improvement.

Yo,
Jim is looking for a 20 meter yagi......
Jim,
If I remember correctly, if you want to optimize a 204BA, look no
further than the Antenna Handbook. I believe they have optimized
element lengths for the Hy-Gain mono-banders.............
