I do "bolt conversions" on a lot of guitars like that. It's a more refined approach to the "New York Reset" or as I call it Hillbilly reset where you cut out a sliver of the back of the heel and run a screw into the block, concealing it with a strap button.
I remove the neck by making a cut between the heel and body, remove material from the heel to attain the proper neck angle, and install brass inserts into the neck heel and run bolts from the inside. Very stable, and since it is way less time consuming than a traditional dovetail reset, it is far less expensive.
Here's one I did. You can see one of the bolts in the second picture... I use two.
