Is it reasonable to:
Add extra grain and water to a batch, boil long enough to sterilize wort then remove low gravity starter wort from batch and freeze starter wort in 500 ml "freezer approved" glass mason Jars. (be sure to let jar cool on counter with lid on before freezing)
When starter wort is needed, let jar thaw on counter for a day then use without boiling?
My thoughts:
Since wort was boiled, most stuff would be boiled out.
Since wort was stored frozen, there is no oxygen for botulism to grow.
Here is a quick demo to calculate how much extra grain to add (in percent) and at what water level the boil should be at when you remove starter wort.
Submit to calculator:
Your target final gravity
Your target final water volume,
Your wanted starter wort gravity
Your wanted starter wort volume
Script will display in far right column at what liquid volume level you should remove your starter wort from the kettle and by how much (in percent) you should increase your grain bill to make up for the starter wort.

Note: I have added this demo to the right of the amazing EZ brewing water calculator just for convience sake.
Also, here is a link to the mason jar faq describing that they are freezer safe
