Just try it
I don't know if this would work, probably yes. But you
can change it later with mount -o remount,size=128m /run

It doesn't need it, it's just the maximum sitze, which it will never reach.

In case of power failure or lockup, the contents are lost, and will not
cause confusion on the next reboot when /run is still populated by
stuff. Just an idea, I do not know if it would really matter.
But it does no harm, so why not juest keep it like it is.

I don't know the details, but I'd think it does not matter. There will
nothing be put into /run that uses a lot of memory, so it will never
actually use its default size of half of your RAM.
