Don't believe it, man. He's a genius!
Ramrods on old rifles were frequently, if not generally, tapered to a smaller diameter on the end that goes into the stock in order to clear that front lock bolt. The front bolt is there to help stabilize the lock, but if the lock is properly inletted, I don't think that front bolt is entirely necessary. I have a flintlock fowling piece with one lock bolt and there have been no issues related to the single bolt.
I would start by tapering the end of the ramrod down some. You may have to make a new rod from a blank, if the original rod has a metal fitting on the end. If that doesn't do the trick, you can use a chainsaw file and cut a little crescent out of the screw body where it passes through the ramrod channel. Use the slot in the screw head to index the screw.
As
@PathfinderNC pointed out, a lot of southern rifles had ramrods in place that protruded past the muzzle. Here is an example:

Many southern rifles had forged iron triggerguards, fastened with screws rather than pins. I think that trait of extra-long appearing ramrods may have been due to the forward triggerguard screw not allowing the rod to go deeper in the stock. Or, it may have just been a southern thing.
I don't think it's a good idea, personally. That protruding ramrod can get caught on things, and in a worst case scenario, this can split the forend of your stock, or tear out the forward ramrod thimble.
The old-time plainsmen, living in areas where there was not any good raw material for ramrods, frequently carried a spare. The best place to carry it was in the bore of the rifle. Long Jack, pictured here, has a spare ramrod that he carries that way:

One final thought is that when you load the rifle, the powder charge and ball will take up a couple of inches in the bore when you ram it, and a jag will also add a little length when you use the rod for cleaning, so the rod need not be excessively long.
Good luck with it! Let us know how this turns out for you.
