What would you do?

Looks good. The flipper was taking up way too much space to begin with...
I've compared the delica and mantras and it's like this. With flipper delete, mantra 3 is comparable to your delica with how much space you get for front two fingers, but the titanium mantra, the space there is more generous, it's closer to endura.
I like the fob for when I spread something on a sandwich, I tend to hold the knife more back on the grip with mantra and with slick scales the lanyard helps. They really want you to just hold that mantra in one grip and do everything in it. With finger on the ramp you know. The titanium m4 version is thinner BTE.

Check out this top picture

Notice how the pivot screw is more in the center visually also.
See I wanted to cut into this area to have even more room for front two fingers.
Then it would expose the liners inside and I wanted to add jimping on the exposed liners.

I also like to mirror polish the spine on some knives.

And if I'd like to have a clip on a delica
I would do this

Thanks for sharing, David! That proposed Amalgam mod sure looks sleek, like a cross between Lance's Waterway blade shape and a flipper deleted Amalgam handle with rounded pommel area. I actually quite like the way the blade profile looks there.

 

I had big Chris change around a knife I sorta liked. Stuff that your asking to do would be easy for the knife makers in the forum.

 

Huge wharnie fan I say carry on!

 

Some choils I've done.
