First of all, kudos to
@dave_person ! A great post, and a kind offer.
I think I'm seeing two questions in
@Brokennock 's original post... First, how to salvage the original tip, and second, where to get a replacement. I think the original tip is still usable, but it'll just have an extra hole in one side. I would agree that a 5/16" rod is really skinny, and if I were to make a new rod, I would do as Dave suggested and start with one the same diameter as the shank of the ramrod tip, cut a shoulder on it and file it down to a light press fit inside the ramrod tip. If the rod is too large for the ramrod pipes, it can be tapered down to fit.
I cross-pin ramrod tips when I install them, but drill a slightly undersized hole in the wood, and enlarge the holes in the metal sleeve to the diameter of the cross pin. Use a toothpick to put some epoxy in the hole and smear a little on the pin and drive it in. When the epoxy has cured, I cut the protruding ends of the crosspin off and file them flush. I don't peen them, and I've never seen one budge.
I don't know of a way to make the extra hole in the original tip invisible. If the tip is epoxied onto a new rod, some of the squeeze-out may fill it, but it will still be visible. However, I don't think the structural integrity of the brass tip is compromised, in any event.
Muzzleloader Builder's Supply has trade gun ramrod tips that are similar to the one on Brokennock's gun, but not identical. His has a really cool, single knurled ring on it, while the tips from MBS have three plain rings. This photo is from their website:

The end has a threaded hole, which you don't see in this photo, and they state that "T
hese tips are made to be installed on a 3/8" ramrod and are caliber specific...," i.e. .58 caliber or .62 caliber. They get $4.50 for these, which I think is reasonable.
I don't own a French trade gun, but I have two Northwest guns. One was from North Star West, and the other from Caywood:

The gun on the right is from NSW and is 20 gauge. That's the original ramrod tip that came with it. The head of the rod is .562" diameter, and the rod is .351", or just a bit less than 3/8". The gun in the middle is from Caywood and is 24 gauge. The original rod that came with it is shown on the left. The head of the brass tip is .530" in diameter, and the rod is .420", slightly less than 7/16". The brass tip is nicely fitted to the rod. This rod had been blackened, and the tail was not tapered. The forward lock bolt impinged on it. I considered tapering the tail, and Danny told me he had "ebonized" the rod with black shoe polish (!) so I could touch up the finish, but I decided instead to just make a new rod from scratch, which is what you see in the gun. It is 1/2" at the tip (the largest diameter hickory rod I could get) tapered down to a good fit in the ramrod pipes and tapered a bit more at the tail to clear the lock bolt. It has a metal tip on the tail end that is threaded for accessories. I think I finished the wood with good old tung-based spar varnish, which is tough, waterproof, and I like the color.
Note that the end of the Caywood ramrod tip is cupped for a ball, while the NSW ramrod tip is flat, for what it's worth. Since I shoot mostly ball in these guns, I cupped the end of my homemade rod slightly. Probably not necessary, but there it is.
Here is a side view of the same guns and rods:

The ramrod tip on the NSW gun looks like a ringer for the one from Muzzleloader Builder's Supply. If you prefer the Caywood tip (the bottom one in the photo), it would not hurt to ask Mr. Caywood directly if he has them for sale. I'm not aware of any other source for them.
I don't know about French guns, but evidently ramrods on some Northwest guns had enlarged metal tips installed. This later-styled Northwest gun, now in the Buffalo Bill Center of the West Collection, was said to have been one of Frederic Remington's studio props. Note the enlarged tip on the ramrod:
