While a folkboat is a rather tender design, adding such additional ballast may also put more stress on the rigging than it was designed for. The greater the righting moment, the less give the boat has for the rigging, and the stronger the rigging needs to be.
I would definitely consider consulting with a marine architect about this, especially if you're looking to open up the keel and add the weigh internally or bolt it on externally. The keelbolt fittings may not be up to the task of supporting that much additional mass and may need to be strengthened to be able to handle it.
IMHO, I would go with adding the weight by re-building the keel with lead ballast rather than trying to add it externally, which will add underwater surface area and slow your boat considerably, as well as possibly increase your draft a bit.
The shot bags, while you're using them, really should be secured so they can not shift in the event of a knockdown or roll over. In the case of either, unless they are secured, they are potential missiles... and could cause you and your boat a lot of damage. They could also prevent the boat from righting itself or slow the righting process, to the point where the downflow through the dorades and such would sink the boat.
You should probably should have consulted with a marine architect about the negative effects of the weight you've added by adding the cedar and mahogany to the cabin roof prior to doing the modification, and may want to ask their advice regarding it now.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
