Well, the menuconfig part I think is best left to another series because it
won't be a simple addition: default file name define would have to
depend on CONFIG_SPLASH_SOURCE, which shouldn't exist as an option
without CONFIG_SPLASH_SCREEN and its related defines, none of which have
a fitting place in the current menuconfig hierarchy. Then there's the
board config file changes these additions would cause.
As for the env variable suggestion though, that can be done.
