Absolutely, you could transplant them if they're not too big. It would
be easier, at this point to put them into new soil rather than trying to
revitalize the soil they are in now.
When I transplant seedlings, I use a Miracle Gro product I think is
called Quick Start and is meant to invigorate the roots. That'll help
your seedlings if you're able to transplant them into new soil.
