My ears are stretched and very thin. Is there any way to thicken up the skin so I can continue wearing large-gauge earrings?

Any maneuver that was performed to thicken the rim of your piercing would usually requires making the piercing a smaller gauge. Once you re-stretch it, that tissue might thin to an even greater degree. Fillers are an option but usually will just plump the tissue. Stretching that area would likely just rearrange the filler and result in no sustainable change to your lobes.

I think it's great that you are planning on getting your gauges fixed. I have done many earlobe repairs as bad or worse than yours with excellent results.  However, don't try to re pierce and stretch them again.  That would create a mess that may be beyond repair.  When you gave decided to get them fixed, just be done with the whole gauge thing and get them repaired properly.  I do many of these repairs and I charge $700 for both ears.  For women, the earlobe can be re pierced , but trying to stretch them out again is a mistake.

Unfortunately, I do not think there are many good options for you in terms of trying to thicken your earlobe skin to allow you to wear large gauge earrings.  It would be possible to surgically alter your earlobe to make the skin thicker, but this would weaken the amount of stretch you could put on the skin and wouldn't allow you to wear large gauge earrings.
