Thanks for the info, it seems my local gunsmith was giving me some BS! I had wanted to keep the Merkel as it has some sentimental value but only if I could convert it. I think I`ll just sell it and put the money towards an English double.

Charly, It has always been my opinion that if a person is new to double rifles it is a smart move to buy a NEW double rifle rather than an old Britt double rifle. The reason for this is, the market for even field grade Britt double rifles is in the clouds in price point. Addtionally, the chance of getting a GOOD double is not likely, unless you are very experienced in the proof markings, and the pit falls of pimped up Britt rifles to make them look like a million dollars. The best Britt doubles are in collections, and the stuff on the market today is pretty rough.
You would be agast at the people who buy these old cammoflaged beaters, and pay collector prices for them, and get really stung with a wall hanger. Besides that, many go into the double rifle world, thinking with a bolt rifle mindset. What I mean by that is, they are used to trying to get all the velocity that can from a perticular cartridge, and look to cartridges like the 375 H&H belted rimless, or the 458 Win Mag in a double rifle, and though new and used double rifle come in those chamberings, these cartridges were designed for bolt rifles, and are not well suited to double rifles.
There are a number of good double rifles that will cost you far less than a worn out Britt, and shoot better as well. Companies like Merkel, Chapuis, Krieghoff, all come new in the under $10K range, and are backed by warenties. They are made of modern steel, and are all as strong as a bank vault. They are are very accurate with a proper put together handload, and as reliable as you can buy. Even B.Searcy will build you a made to fit "YOU" field grade double rifle for under $10K. It is a no frills rifle but made to fit your personal measurements. The only fly in the ointment there is the 8 mo wait to get it with half down. However even a used Searcy can be sent to Butch for repair, and he houners the warenty even though you didn't buy the rifle from him. That is a big plus for B.Searcy's rifles, he stands behind his product, and he is in Baron, Califirnia, not outer mongolia.
If I were you what I would do is, buy a good used Merkel, or Chapuis S/S double rifle chambered for 9.3X74R, and about 100 rounds of S&B 286 gr ammo, and find out if you are a double rifle person. That cartridge is good for anything in North America, including the big Coastal Brown bears of Alaska, and is cheap to shoot, has pleanty flat trejectory, and is fine for all plains game in Africa, and is even legal for the big five in many places in Africa. That rifle is light for a double, and handles like a good shotgun.
On the ammo side of this affair, Federal factory ammo for a 470NE double rifle sells fro $380.oo per box of 20 rounds! That is $16.oo every time you pull the trigger. The Sellier& Bellot 9.3X74R sells for about $45.oo per box of 20 and is about $2.25 per shot! Of course handloading of either of these rounds will save you lots of money, and once you find the load that shoots to the regulation built into the rifle, you will be getting the best the rifle has to offer.
What ever you decide to do, give me a shout, and I'll try to tell you what to look for when you find something you may want to buy!
Just some things to think about before you dive into water where you don't know the depth.
