Isn't the default to purge /tmp on reboot normally anyway?
man rcS
TMPTIME
On boot the files in /tmp will be deleted if their modification
time, file status time and access time are all at least TMPTIME
days ago. A value of 0 means that files are removed regardless
of age. If you don't want the system to clean /tmp then set
TMPTIME to a negative value (e.g., -1) or to the word infinite.
And I believe the default is 0. I am not setting it and my /tmp is
always purged on reboot. If you want more persistent storage then
saving the file in /var/tmp is better. The contents there are
preserved across a reboot.
Since /tmp is purged on a reboot that isn't a negative for it being a
tmpfs which being in ram is also purged on reboot.
The usual problem with /tmp being a tmpfs is file system size. When
it is real storage on disk you can do video editing of large files
there within the size of the file system. But a tmpfs is usually much
smaller and not large enough for that. The size problem was often
discussed here a year or so ago when tmpfs became popular for /tmp.

But maybe I am not understanding what you are suggesting.
