What you have to be careful of is doing a cosmetic restoration of the tenon which ends up weaker than the original.
The critical area for resisting the pull of the strings and impact is the back of the neck heel where the tenon has failed and if you dowel it the crossection of the dowel is likely to be less than half the original Tenon
If you do not have the skills and tools to make a really strong repair using wood, perhaps you are better off using the existing hole and a bigger and longer wood screw to hold it Whilst not a professional repair it is reversible and you already have a hole there

Whilst a bigger tenon is a very good thing, and I would certainly go that way, if you dowel it to the existing neck, there will be a weak point right where it has failed before.
I would be inclined to cut away the base of the heel parallel to the fingerboard for about half the depth of the heel then glue on a new piece of mahogany to form the heel and tenon.
This will probably look better than patching the dowel hole and will certainly be stronger

If you are reallygood with a chisel (or very slow and careful)you could cut a pocket for the new tenon from the existing face of the heel. Just drill out the bulk of the material then trim to size.
BTW use a stronger wood than mahogany for the tenon (hard Maple?)
Prostheta's sketch for the enlarged tenon looks like a good idea to me as long as the neck block does extend all the way to the pickup hole
