I would tend to think that it would be no problem to use batteries in a
parallel fashion, but it would be advisable to start out with fresh
batteries for both legs of the parallel circuit.  I'm not familiar with how
the charging system is set up, but it would need to have an appropriate
current capacity.

Here's another idea for you, if you're interested.  If there's room for
another battery pack, it might be less radical to add the additional battery
circuit with a switch to change back and forth between the two.  If they're
put in with the design that they'll never be operational at the same time,
it wouldn't have any affect on the charging circuit at all.  Switch in one
position, it uses and charges one battery pack.  Switch in the other
position, it uses and charges the other battery pack.  Sort of like a second
gas tank on your truck.

There are no doubt dozens of possible variations.

Just a thought.
