Advice for my ballast on my Sanger V215

This is how I weigh my boat now and I love it.

I want to keep the same weight, but the issue I have is I have so much lead in the boat I can't trailer it without taking the lead out. Or run the boat for cruising with out the extra weight. Plus, just sometimes, others ask me to turn down the wake. LOL! Even after I empty the stock ballast and I am left with just lead, the wake is still pretty good. So my question to you all is what do I do to reduce the lead? Below are my dimensions for my lockers. For now I am just interested in changing the rear ballast. I will attempt something for the bow later.

Thanks for any advice or help! One thing that will suck for sure about lead vs bags is, I will lose all of the storage I have in those lockers.
