Helical inserts in Suhl

In the near future I'll be ordering a helical thread insert kit to fix a takedown screw hole in a rifle that I successfully stripped (got Devcon into the screw hole and the screw bottomed out).

The question in my mind is this- would it be a bad idea to go ahead and put the same helicoil inserts in my Suhl? The reason would be convenience. I'm putting 1/4x28 inserts into the rifle that needs work, and it is much easier and cheaper to find 1/4x28 screws as opposed to the 6x75mm screws that the Suhl uses. The Suhl definitely isn't broke and thus doesn't need fixing, however is the convenience of using readily available screws worth putting helical inserts into the receiver? This is important to me because I'm going to be working on a couple of stock patterns for the Suhl this spring/summer and getting a few custom made screws wouldn't be cheap.

For the record, here's the kit I'll be using:

I wouldn't want to use helical inserts in something like a round receiver because the wall thickness and therefore thread depth is against you IMO.

I looked into drilling and tapping my Suhl to 1/4-28 but the hole is too big already. IMO the best bet is to bite the bullet and order the correct screws. JP will make them with extra thread length so you can cut them to length to fit your app.

If the hole is stipped as you said, replacing the screws solves nothing.

That's not exactly what I'm doing... I'm buying the kit to fix another rifle with a stripped hole and I'll be using 1/4x28 inserts. Because I'll have the kit anyways, I am considering going ahead and putting the inserts into my Suhl receiver so I can use common 1/4x28 screws for it.
 
unless helicoil has something I'm not aware of, they work best in blind holes,
or held just short of the opposite surface. There is a drive spur at the end
and if that comes thru in an area which is not accessible, you cannot cut
or grind it off. It just kinda unravels.
