If you do not want to be able to remove them then just slide them on the tube up against the fuselage, draw an outline on the fuselage of the stabs, slide them off the tube, cut the covering away just inside your outline and epoxy the stab to both the tube and fuselage
If you want them removeable, then I'll let someone else suggest it

My short lived Aeroworks 33% Extra 330L had the stabs modified ala Carden and Extreme Flight to be more easily removeable and solidly attached. The root rib was routed out and new root rib with tabs was created for the new space. The was simply glued in place and painted white to match. Once the incidence is set simply use the holes in the tabs as guide for the holes in the fuse. Light ply with blind nuts glued into the fuse should finish the job (assuming that area is sheeted). If the area is not sheeted then making something to hold the blind nuts could be interesting...

Your other option is to make another root rib for each stab out of 1/8" aircraft ply. Make them with the tabs you like and glue them to each stab. Then do as GalenB suggested. They will add weight you likely don't want but they will do the job quite effectively. Course if the plane now has a nose weight problem this could be part of the cure.

RE: Please Help--Removable Stabs on BME Edge
Not to interupt but I have a set of wings in near new condition from My BME Edge that I flew last summer. The plane finally got munched but the wings are in great shape. I think there's one small ding in the leading edge of one panel. Overall they look great and have no structural damage. It's the original version not the Edge II. I'd let them go real cheap and ship them. I have the right boxes tho ship them in so let me know if I can help anyone. I'll post pics if anybody want's.

After looking more closely at your drawings I think just scabbing in the section with the attachment tab will work fine. I would suggest either doing two such tabs or another alignment dowel closer to the trailing edge. As your drawing shows all of the things that resist twisting around the tube/spare are near the front and the rear is unsupported.

I use dowel hard points expoxied into the stabs for retention of same. A blind nut is installed on one side of the dowel and I tighten/lock the cap screw against it with a serrated washer sandwiched between the blind nut and cap screw, the cap screw protrudes into the aluminum stab tube. Every GS model I have uses this retention method on the stabs and some on the wings too. I have never had one fall out, if you’re concerned you can out a piece of clear tape over the screw for added protection.
You can do this work with little effort and cosmetically it's very clean if you pay attention. Just a small round piece of covering hides the dowel. If there are hard points in place I use a brass thread insert in lieu of the blind nut.

The drawing below shows my method for stab retention. I'm using this method with my Carden models and have for many years together with the incidence locators which are essentially a plastic "L" bracket bolted to the stab through a small lite-ply plate glued to the bottom of the stab and then threw the fuse.
I also use two 1/4" aluminum studs/dowels and plastic knobs to retain the wings now days.
