Probably this is the most reasonable direct way to go, to introduce "desktop builder(s)"!
It will get all "small" packages already built from regular builders. It will crunch
heavy desktop ports with only single poudriere builder, but with all available cores given to
MAKE_JOBS!
Note that such setup is almost opposite to "regular builders" that have a small
amount of cores per poudriere builder, but large number of poudriere builders!

If it scales good further, 96 cores will manage electron in one hour! :)
What I've done in the past is to have the first build run of all the massive
ports to be built, with a high -J, tmpfs=all and every port in the list
configured in poudriere.conf to not build these massive ports simultaneously.
Then have another build run for all the other ports, which completes
relatively quickly because the prerequisites for many things are
already available.
This at the time resulted in a greater chance of all ports being built.
I think the total time (massive-ports-build+regular-build) may be less
but I'd have to check.
It seems to me that some ports fight each other when J =>2 and even this
320GB 20 CPU system will run out of resources (typically swap) if the build
runs with the complete portsbuild list in one go. The above build never hit
swap.
