Nothing crazy about it, if it's a good gun, and you like it, and are confident using it, thats what counts.
I'm assuming it's a Savage 94? Good guns, and if you have had it bored out to improved cylinder, thats exactly how Remington bores their smoothbore slugguns, so you probably have an ideal candidate there.
I'm sure you could find a smith to drill and tap the barrel, but you might want to ask him about epoxy also. If he can come up with a weaver base that has the proper radius for the barrel, there are epoxies out there that will bind the base to the barrel like steel, yet you can loosen them up with a heat temperature of about 300 degrees, that way if you ever wanted to remove it, the gun would still be original without the holes, I suggest you ask him the best way to go about it, good luck, and let us know how it shoots when scoped if you do go through with it.
